GIFT OF BIOLOGY LIBRARY G STATISTICAL METHODS WITH SPECIAL REFERENCE TO BIOLOGICAL VARIATION. BY C. B. DAVENPORT, Head of Department of Experimental Biology and Director of Station for Experimental Evolution of the Carnegie Institution. SECOND, REVISED EDITION. FIRST THOUSAND. NEW YORK : JOHN WILEY & SONS. LONDON : CHAPMAN & HALL, LIMITED. 1904. Copyright, 1889, 1904, BY C. B. DAVENPORT. | i > 3 BIOLOGY LIBRARY G ROBERT DRUMMOND, PRINTER, NEW YORK. PREFACE. THIS book has been issued in answer to a repeated call fora simple presentation of the newer statistical methods in their application to biology. The immediate need which has called it forth is that of a handbook containing the working formulae for use at summer laboratories where material for variation - study abounds. In order that the book should not be too bulky the text has been condensed as much as is consistent with clearness. This book was already in rough draft when the work of Duncker appeared in Roux's Archiv. I have made much use of Duncker's paper, especially in Chapter IV. I am indebted to Dr. Frederick H. Safford, Assistant Professor of Mathe- matics at the University of Cincinnati and formerly Instructor at Harvard University, for kindly reading the proofs and for valuable advice. To Messrs. Keuffel and Esser, of New York, I am indebted for the use of the electrotypes of Figures 1 and 2. Finally, I cannot fail to acknowledge the cordial cooperation which the publishers have given in making the book ser- viceable. C. B. DAVENPORT. BIOLOGICAL LABORATORY OF THE BROOKLYN INSTITUTE, COLD SPRING HARBOR, LONG ISLAND, June 29, 1899. iii 250822 PREFACE TO THE SECOND EDITION. THE first edition of this book having been favorably re- ceived, the publishers have authorized a revised edition embodying many of the new statistical methods elaborated chiefly by Professor Karl Pearson and his students and associates, and presenting a summary of the results gained by these methods. These, while increasing somewhat the bulk of the book, have, it is hoped, rendered it more service- able to investigators. Too much emphasis can hardly be laid on the debt that Biometricians owe to Professor Pear- son's indefatigable researches in the new science of Biome- try— especially in the development of Statistical Theory. The publishers, also, of this book are deserving of credit for the courage they have shown in reproducing expensive tables for the use of a still very limited body of statistical workers. Especial attention is called to Table IV, which is an extension of Table IV of the first edition that was cal- culated by Professor Frederick H. Safford, and appears to have been the first published table of the normal probability integrals based on the standard deviation. More recently Mr. W. F. Sheppard has published in Biometrika a similar table in which, however, the tabular entries are given to seven places of decimals, while the arguments are given to two decimal places only. In the present table the argu- ments are subdivided to three places of decimals and with the aid of the table of proportional parts interpolation is easily effected. Especial acknowledgment must be made of assistance received from my friend Mr. F. E. Lutz, who read over the entire manuscript and contributed certain of the numerical examples.

ON METHODS OF MEASURING ORGANISMS. Preliminary Definitions. An individual is a segregated mass of living matter, capable of independent existence. Individuals are either simple or compound, i.e., stocks or corms. In the case of a compound individual the morphological unit may be called a person. A multiple organ is one that is repeated many times on the same individual. Example, the leaves on a tree, the scales on a fish. A character is any quality common to a number of indi- viduals or to a number of multiple organs of one individual. A variate is a single magnitude-determination of a character. Integral variates are magnitude-determinations of charac- ters which from their nature are expressed in integers. Such magnitudes are expressed by counting; e.g., the number of teeth in the porpoise. These are also called discontinuous. Graduated variates are magnitude-determinations of char- acters which do not exist as integers and which may conse- quently differ in different variates by any degree of magni- tude however small; e.g., the stature of man. A variant, among integral variates, is a single number-con- dition, e.g., 5 (flowers), 13 (ray-flowers), etc. A class, among graduated variates, includes variates of the same or nearly the same magnitude. The class range gives the limits between which the variates of any class fall. Individual variation deals with diversity in the characters of individuals. Organ variation, or partial variation, deals with diversity in multiple organs in single individuals. 1 2 STATISTICAL METHODS. Methods of Collecting Individuals for Meas- urement. In collecting a lot of individuals for the study of the varia- bility of any character undue selection must be avoided. The rule is: Having settled upon the general conditions, of race, sex, locality, age, which the individuals to be measured must fulfil, take the individuals methodically at random and without possible selection of individuals on the basis of the magnitude of the character to be measured. If the individuals are simply not consciously selected on the basis of magnitude of the character they will often be taken sufficiently at random. The number of variates to be obtained should be large; if possible from 200 to 2000, depending on abundance and variability of the material. Processes Preliminary to Measuring Characters. Some characters can best be measured directly; e.g., the stature of a race of men. Often the character can be better studied by reproducing it on paper. The two principal methods of reproducing are by photography and by camera drawings. For photographic reproductions the organs to be measured will be differently treated according as they are opaque or transparent. Opaque organs should be arranged if possible in large series on a suitable opaque or transparent back- ground. The prints should be made on a rough paper so that they can be written on ; blue-print paper is excellent. This method is applicable to hard parts which may be studied dry; e.g., mollusc shells, echinoderms, various large arthro- pods, epidermal markings of vertebrates and parts of the vertebrate skeleton. Shadow photographs may be made of the outlines of opaque objects, such as birds' bills, birds' eggs, and butterfly wings, by using parallel rays of light and inter- posing the object between the source of light* and the photo- * A Welsbach burner or an electric light are especially good. Minute MEASUREMENT OF ORGANISMS. 3 graphic paper. More or less transparent organs, such as leaves, petals, insect-wings, and appendages of the smaller Crustacea, may be reproduced either directly on blue-print paper or by "solar prints," either of natural size or greatly enlarged. For solar printing the objects should be mounted in series on glass plates. They may be fixed on the plate by means of balsam or albumen and mounted between plates either dry or in Canada balsam or other permanent mounting media. Wings of flies, orthoptera, neuroptera, etc., may be prepared for study in this way; twenty-five to one hundred sets of wings being photographed on one sheet of paper, say 16 X 20 inches in size. Microphotographs will sometimes be found service- able in studying small organisms or organs, such as shells of Protozoa or cytological details. Camera drawings are a convenient although slow method of reproducing on paper greatly enlarged outlines of microscopic characters, such as the form and markings of worms and lower Crustacea, sponge spicules, bristles, scales and scutes, plant- hairs, cells and other microscopic objects. In making such camera drawings a low-power objective, such as Zeiss A*, will often be found very useful. The Determination of Integral Variates.— Methods of Counting. While the counting of small numbers offers no special diffi- culty, the counting becomes more difficult with an increase of numbers. To count large numbers the general rule is to di- vide the field occupied by the numerous organs into many snail fields each containing only a few organs. Counting under the microscope, e.g., the number of spines, scales or plant-hairs per square millimetre, may be aided by cross-hair rectangles in the eyepiece. The number of blood-corpuscles in a drop of blood, or of organisms in a cubic centimetre of water, have long been counted on glass slides ruled in small squares. electric lamps such as are fed by a single cell give sharp shadows of small objects. STATISTICAL METHODS. The Determination of Graduated Variates,— Methods of Measurement. Straight lines on a plane surface are easily meas- ured by means of a measuring-scale of some sort. The meas- urement should always be metric because this is the universal scientific system. Vari- ous kinds of scales may be obtained of optical companies and hardware dealers, — such as steel measuring tapes, graduated to millimetres (about $1.00), and steel rules (6 cm. to 15 cm. ) graduated to £ of a milli- metre. Steel "spring-bow" dividers with milled-head screw are useful for getting distances which may be laid off on a scale. Tortuous lines, e.g., the contour of the serrated margin of a leaf or the outer margin of the wing of a sphinx moth, may be measured by a map-measurer ("Entfer- nungsmesser," Fig. 1), supplied at artist's and engineer's supply stores at about $3.50. Distances through solid bodies or cavities are measured by calipers of some sort. Calipers for measuring diameters of solid bodies are made in various styles. Micrometer screw calipers (" speeded") reading to one-hundredths of a millimetre and sold by dealers in physical apparatus for about $5.00 are excellent for determining diameters of bones, birds' eggs, gastropod shells, etc. Leg calipers for rougher work can be obtained for from 30 cents to $4.00. The micrometer " caliper-square," available for inside or outside measurements and measuring to hundredths of a millimetre, is a useful instrument.* The area of plane surfaces, as, e.g., of a wing or leaf, is easily determined by means of a sheet of colloidin scratched in millimetre squares. By rubbing in a little carmine the * Many of the instruments described in this section are made by the Starrett Co., Athol, Mass., and by Brown and Sharpe, Providence, tool cutters. FIG. 1. MEASUREMENT OF ORGANISMS. 5 scratches may be made clearer. The number of squares covered by the surface is counted (fractional squares being mentally summated) and the required area is at once obtained. If the area has been traced on paper it may be measured by the planimeter (Fig. 2). This instrument may be obtained at FIG. 2. engineer's supply shops. It consists of two steel arms hinged together at one end; the other end of one arm is fixed by a pin into the paper, the end of the second arm is provided with a tracer. By merely tracing the periphery of the figure whose area is to be determined the area may be read off from a drum which moves with the second arm. This method is less wearisome than the method of counting squares. The area of a curved surface, like that of the elytra of a beetle or the shell of a clam, is not always easy to find. To get the area approximately, project the curved surface on a plane by making a camera drawing or photograph of its outline. By means of parallel lines divide the outline draw- ing into strips such that the corresponding parts of the curved surface are only slightly curved across the strips, but greatly curved lengthwise of the strips. Measure the length of each plane strip and divide the magnitude by the magnification of the drawing. Measure also, with a flexible scale, the length of the corresponding strip on the curved surface. Then, the area of any strip of the object is to the area of the projection as the length of the strip on the object is to the length of its projection. The sum of the areas of the strips will give the total area of the surface. 6 STATISTICAL METHODS. Characters occupying three dimensions of space may be quantitatively expressed by volume. The volume of water or sand displaced may be used to measure volume in the case of solids. The volume of water or sand con- tained will measure a cavity. Irregular form is best measured by getting, either by means of photography or drawings, pro- jections of the object on one or more of the three rectangular fundamental planes of the organ, and then measuring these plane figures as already described. Or two or more axes may be measured and their ratio found. Characters having weight are easily measured ; the only precautions being those observed by physicists and chemists. Color Characters. Color may be qualitatively ex- pressed by reference to named standard color samples. Sucl} standard color samples are given in Ridgeway's book, " Nomenclature of Color," and also in a set of samples manu- factured by the Milton Bradley Co., Springfield, Mass., costing 6 cents. The best way of designating a color character is by means of the color wheel, a cheap form of which (costing 6 cents) is made by the Milton Bradley Co. The colors of this "top" are standard and are of known wave-length as follows: Red, 656 to 661 Green, 514 to 519 Orange, 606 to 611 Blue, 467 to 472 Yellow, 577 to 582 Violet, 419 to 424. It is desirable to use Milton Bradley's color top as a standard. Any color character can be matched by using the elementary colors and white and black in certain proportions. The pro- portions are given in percents. In practice the fewest possible colors necessary to give the color character should be employed and two or three independent determinations of each should be made at different times and the results averaged. So far as my experience goes any color character is given by only one least combination of elementary colors. (See Science, July 16, 1897.) When there is a complex color pattern the color of the different patches must be determined separately. In case of a close intermingling of colors, the colored area may be rapidly rotated on a turntable so that the colors blend and the result- MEASUREMENT OF ORGANISMS. 7 ant may then be compared with the color wheel. By this means also the total melanism or albinism, viridescence, etc., may be measured. Marking-Characters. The quantitative expression of markings or color patterns will often call for the greatest ingenuity of the naturalist. Only the most general rules can here be laid down. Study the markings comparatively in a large number of the individuals, reduce the pattern to its simplest elements, and find the law of the qualitative variation of these elements. The variation of the elements can usually be treated under one of the preceding categories. Find in how far the variation of the color pattern is due to the variation of some number or other magnitude, and express the variation in terms of that magnitude. Remember that it is rarely a ques- tion whether the variation of the character can be expressed quantitatively but rather what is the best method of express- ing it quantitatively. Aids in Calculating1. An indispensable aid in multi- plying and dividing is a book of reckoning tables of which Crelle's Rechnungstafeln (Berlin: Geo. Reimer) is the best. This work enables us to get directly any product to 999 X 999 and indirectly, but with great rapidity, any higher product or any quotient. The tables of Barlow (" Tables of Squares, Cubes, Square Roots, Cube Roots, and Reciprocals of all Integer Numbers up to 10,000") are like our Table X, but more extended. The tedious work of adding columns of numbers is greatly simplified by the use of some one of the better adding ma- chines. There are many forms, of which the best are made in the United States. The author has used the " Comp- tometer" made by the Felt and Tarrent Manufacturing Co., Chicago ($125), and found it perfectly satisfactory. This machine is manipulated by touching keys, as in a typewriter, but it does not print the numbers touched off. In this respect it is inferior to the Burroughs Adding Machine of the Ameri- can Arithometer Co., St. Louis, Mo., which costs $250 to $350, or to the Standard Adding Machine, St. Louis ($185). For the multiplication and division of large numbers the Baldwin Calculator is well spoken of (Science, xvn, 706). It is sold by the Spectator Company, 95 William Street, New York, price $250. The same firm is agent for Tate's Im- 8 STATISTICAL METHODS. proved Arithometer ($300 to $400). The "Brunsviga" cal- culating machine (Herrn Grimme, Natalis & Co., Brunswick, Germany, Manufacturers; price $140 to & 75) is highly recom- mended by Pearson. To draw logarithmic curves and for the mechanical solu- tion of arithmetical problems the instrument of Brooks (Science, xvn, 690, not yet marketed) should be found useful. Precautions in Arithmetical Work. Even the most careful computers make mistakes in arithmetical work. It is absolutely necessary to take such precautions that errors may be detected. The best method is for statistical workers to compute in pairs, but absolutely independently, comparing results as the work progresses, so that time shall not be wasted by elaborate work done with erroneous values. In case of disagreement both workers should recompute, start- ing from that point of the work where their results check. In cases where it is not feasible for the work to be done by two people, it should be calculated on distinct pages of the note- book— proceeding through several steps on the one page and then independently through the same steps on another page; checking the work as it progresses. It will be found useful as the work progresses to make rough checks by comparing the results with the original data to see that the results are probable. Neatness in arrangement of work and in the making of figures is essential. It is best to make all calculations in a book with pages about 20 cm. by 30 cm., quadruple ruled, with about three squares to the centimetre, so that each figure may occupy a distinct square. I like to work with a pencil, of 2H grade, so that slight errors may be erased and rectified. In case of larger errors running through several steps of the work, the erroneous calculations should not be erased but cancelled. In using logarithms with the six-place table given in this book, it is ordinarily necessary to write the entire mantissa to six places, and to determine the number corresponding to any logarithm to at least six places by use of the table of proportional parts given at the bottom of the page. Upon the completion of the calculation the number of decimal places cO be recorded will depend upon the probable* error of MEASUREMENT OF ORGANISMS. 9 each constant. It will ordinarily suffice if the probable error contain two significant figures, e.g., ±0.17 or ±0.0089; then the constant will be carried out to the same number of places and not farther. 10 STATISTICAL METHODS. CHAPTER II. ON THE SERIATION AND PLOTTING OP DATA ANJD THE FREQUENCY POLYGON. The data obtained by measuring any character in a lot of individuals consists either of amass of numbers for the charac- ter in each individual ; or, perhaps, two numbers which are to be united to form a ratio ; or, finally, a series of numbers such as are obtained by the color wheel, of the order : TF40#, N (Black) 38#, 7 12$, Q 101 The first operation is the simplifi- cation of data. Each variate must be represented by one number only. Consequently, quotients of ratios must be de- termined and that single color of a series of colors which shows most variability in the species must be selected, e.g.,N. The process of seriation, which comes next, consists of the grouping of similar magnitudes into the same magnitude class. The classes being arranged in order of magnitude, the number of variates occurring in each class is determined. The number of variates in the class determines the frequency of the class. Each class has a central value, an inner and an outer limiting value, and a certain range of values. The method of seriation may be illustrated by two examples ; one of integral variates, and the other of graduated variates. Example 1. The magnitude of 21 integral variates are found to be as follows : 12, 14, 11, 13, 12, 12, 14, 13, 12, 11, 12, 12, 11, 12, 10, 11, 12, 13, 12, 13, 12, 12. In seriation they are arranged as follows : Classes: 10,11,12,13,14. Frequency : 1, 4, 11, 4, 2. Example 2. In the more frequent case of graduated variates our mag- nitudes might be more as follows : 3.2 4.5 5.2 5.6 6.0 3.8 4.7 5.2 5.7 6.2 4.1 4.9 5.3 5.8 6.4 4.3 5.0 5.3 5.8 6.7 4.3 5.1 5.4 5.9 7.3 In this case it is clear that our magnitudes are not exact, but are merely approximations of the real (forever unknowable) value. The question SERIATIO^ AND PLOTTING OF DATA. 11 arises concerning the inclusivencss of a class — the cZa.ss range. An approximate rule is : Make the classes oni}- just large enough to have no or very few vacant classes in the series. Following this rule we get Classes Frequency Classes.... Frequency The classes are named from their middle value, or better, for ease of subsequent calculations, by a series of small integers (1 to 9). In case the data show a tendency of the observer towards estimating to the nearest round number, like 5 or 10, each class should include one and only one of these round numbers. As Fechuer ('97) has pointed out, the frequency of the classes and all the data to be calculated from the series will vary according to the point at which we begin our seriation. Thus if, instead of beginning the series with 3.0 as in our example, we begin with 3.1 we get the series : 3.0-3.4; 3.5-3.9; 4.0-4.4; 4.5-4.9; 5.0-5.4; 3.2 3.7 4.2 4.7 5.2 1 Q 3 4 5 1 1 3 3 7 5.5-5.9; 6.0-6.4; 6.5-6.9; V.0-7.4; 5.7 6.2 6.7 7.2 6 7 8 9 5 3 1 1 Classes — ( 3.1-3.5; "j 3.3 3.6-4.0; 3.8 4.1-4.5; 4.3 4.6-5.0; 4.8 5.1-5. 3.5 Frequency 1 1 4 3 6 Classes ( 5.6-6.0; 6.1-6.5; 6.6-7.0; 7.1-7.5; ( 5.8 6.3 6.8 7.3 Frequency 6 2 1 1 which is quite a different series. Fechner suggests the rule: Choose such a position of the classes as will give a most normal distribution of fre- quencies. According to this rule the first distribution proposed above is to be preferred to the second. In order to give a more vivid picture of the frequency of the classes it is important to plot the frequency polygon. This is done on coordinate paper.* The best method, especially when the number of classes is less than 20, is to represent the frequencies by rectangles of equal base and of altitude proportional to the frequencies. Lay off along a horizontal line equal contiguous spaces each of which shall represent one class, number the spaces in order from left to right with the class magnitudes in succession, and erect upon these bases rectangles proportionate in height to the frequency of the respective classes (Fig. 3). * This paper may be obtained at any artists' supply store. 12 STATISTICAL METHODS. This method of drawing the frequency polygon is known as the method of rectangles. When the number of classes is large the frequencies may be represented by ordinates as follows : At equal intervals along 1 , , 3.0 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 FIG. 3. a horizontal line (axis of -X") draw a series of (vertical) ordi- nates whose successive heights shall be proportional to the frequency of the classes. Join the tops of the ordinates as shown in Fig. 4. This method of drawing the frequency polygon is known as the method of loaded ordinates. 2600 LEAVES -NORMAL CURVE Q280 HI E NUMBER OF V£!NS FIG. 4. — VEINS IN BEECH LEAVES, AFTER PEARSON, '02*'. The rejection of extreme variates in calculating the constants of a distribution polygon is to be done only rarely and with caution. In many physical measurements Chauvenet's criterion is used to test the suspicion that a single extreme variant should be rejected. A limiting devia- tion (KG) is calculated. K is the argument in Table IV cor- responding to a tabular entry equal to — - — • SERIATION AND PLOTTING OF DATA. 13 EXAMPLE. — In 1000 minnows from one lake there are found the following frequencies of anal fin-rays: 7 1 8 2 9 10 11 15 279 554 A = 10.835 ; o = .728 fin-rays. 1999 ._n__ "= 77^ =.49975. 12 144 13 5 Looking in Table IV we find 3.48 corresponding to the entry 49975. Then the limiting deviation = 3. 48 X. 728 = 2.5334 and the limiting class is 10.835 — 2.533=8.302; hence the observation at 7 might be excluded in calculating the constants of the seriation ; but it should not be sup- pressed in publishing the data. CERTAIN CONSTANTS OF THE FREQUENCY POLYGON. After the data have been gathered and arranged it is neces- sary to determine the law of distribution of the variates. To get at this law we must first determine certain constants. The average or mean (A) is the abscissa of the centre of gravity of the frequency polygon. It is found by the formula in which V is the magnitude of any class; / its frequency; I indicates that the sum of the products for all classes into frequency is to be got, and n is the number of variates. Thus in the example on p. 10: A =(3.2X1+3.7X1+4.2X3-1-4.7X3 + 5.2X7+5.7X5+6.2X3 + 6.7 XI +7.2 XI) -^25 = 5.24, or AI = (IX 1+2 XI +3X3 +4X3 +5X7 +6X5 +7X3+8X1+ 9X1) -*- 25=5.08, A =5.2* + .08(5.7 -5.2) =5.24. ' A still shorter method of finding A is given on page 20. The mode (M) is the class with the greatest frequency. It is necessary to distinguish sharply between the empirical and the theoretical mode. The empirical mode is that mode which is found on inspection of the seriated data. In the example, the empirical mode is 5.2. The theoretical mode is the mode of the theoretical curve most closely agreeing with the observed distribution. Pearson 1902b, p. 261) gives this * 5.2 is the true class magnitude corresponding to the integer 5, 14 STATISTICAL METHODS. rule for roughly determining the theoretical mode. The mode lies on the opposite side of the median from the mean ; and the abscissal distance from the median to the mode is double the distance from the median to the mean; or, mode=mean — 3 X (mean — median). More precise directions for finding the mode in the different types of frequency poly- gons are given in the discussion of the types. The median magnitude is one above which and below which 50% of the variates occur. It is such a point on the axis of X of the frequency polygon that an ordinate drawn from it bisects the polygon of rectangles or the continuous curve, but not the polygon of loaded ordinates. To find its position: Divide the variates into three lots: those less than the middle class, i.e., the one that contains the median magnitude, of which the total number is a; those of the middle class, b; and those greater, c. Then a + b + c = n — the total number of variates: Let V = the lower limiting value of the middle class, and I" = the upper limiting value, and let x = the abscissal distance of the median ordinate above the lower limit or below the upper limit of the median class according as x is positive or negative. Then \n — a : b = x : I" — I' when x is positive, or \n — c : b = x : I" — V when x is negative. Thus in the last example: (12.5-8): 7=x : 0.5; #=.32; the median magnitude = 5.0 + .32 = 5. 32. Or (12.5-10): 7 = -x : 0.5; x=-.18\ the median magnitude =5. 5 -.18 = 5. 32. (Cf. p. 10.) The probable error (E) of the determination of any value gives the measure of unreliability of the determina- tion; and it should always be found. For, any determination of a constant of a frequency polygon is only an approximation to the truth. The probable error (E) is a pair of values lying one above and the other below the value determined. We can say that there is an even chance that the true value lies between these limits. The chances that the true value lies within :* ±2#are 4.5:1 ±5E are 1,310:1 ±3Eare21 :1 ±6E are 19,200:1 ± 4E are 142 : 1 ± 7E are 420,000 : 1 iCEare 17,000,000:1 are about a billion to 1.

The determination of which it is the error should be carried out to the same number of places as the probable error and no more. The probable difference between two averages (A1 and A 2) of which the probable errors (El and E2) are known is the square root of the sum of the squared probable errors, or (Pearson, '02): Probable Difference ot A,-A2 is \/E* + E*.

Simple. 1. Range unlimited in both directions: a. Symmetrical. The normal curve. b. Unsym metrical (Pearson's Type IV). 2. Range limited in one direction, together with skewness (Types III, V, and VI). 3. Range limited in both directions : a. Symmetrical, Type II. b. Unsymmetrical, Type I. II. Complex. B. Multimodal. The classification of any given curve is not always an easy task. Whether the curve is unimodal or multimodal can be told by inspection. Whether any unimodal curve is simple or complex cannot be told by any existing methods without great labor and uncertainty in the result. Complex curves may be classified as follows : 1. Composed of two curves, whose modes are different but so near that the component curves blend into one ; such curves are usually unsym- metrical. 2. The sum of two curves having the same mode but differing varia- bility. 3. The difference of two curves having the same mode but differing variability. If the material is believed to be homogeneous and the curve is unimodal it is probably simple and its classification may be carried further. For classification the rule is as follows : Determine the mean of the magnitudes. Take a class near the mean (call it F0) 20 STATISTICAL METHODS. as a zero point ; then the departure of all the other classes will be - 1, - 2, - 3, etc., and + 1, -f 2, -f 3, etc. Add the products of all these departures multiplied by the frequency of tbe corresponding class and divide by n; call the quotient rt. Add the products of the squares of all the departures multi- plied by the f-requency of the corresponding class and divide by n\ call the quotient v^. Add the products of the cubes of all the departures multiplied by the frequency of the corresponding class and divide by n\ call the quotient r3. Add the products of ih&fourtfi powers of all the departures multiplied by the frequency of the corresponding class and divide by ?i; call the quotient r4. Or, 2(y— V ) ••', = — — = departure of VQ from mean. V0 being known, A may be found [A = 1 The values rlf r9t ra, v4, are called respectively the first, second, third, and fourth moments of the curve about Fo. To get the moments of the curve about the mean, either of two methods (A or B) will be employed. Method A is used when integral variates are under consideration ; method B when we deal with graduated variates.

The normal curve is symmetrical about the mode; con- sequently the mode and the median and mean coincide. The mathematical formula of the normal curve, a formula much used. jFi = 2/?2 — 3ft — 6. The classification was given as follows: /?i>0, curve is of Type I. Pi =0, /?2<3, curve is of Type II. /?i> 0, /?2> 3, curve is of Type III. ft =0, ,52 = 3, curve is normal.

To compare any observed curve with the theo- retical normal curve we can make use of tables. For the case of a polygon of loaded ordinates the theoretical fre- x quency of any class at a deviation — from the mean can be taken directly from Table III. Here — is the actual devia- tion from the mean expressed in units of the standard devia- tion, and — the corresponding ordinate, y0 being taken as 2/o equal to 1, and a is the standard deviation. For the case of a polygon built up of rectangles represent- ing the relative frequency of the variates, Table IV gives immediately the theoretical number of individuals occurring between the values x=Q and x= ±—. By looking up the given values of — the corresponding theoretical percentage of variates between the limits x=0 and x= db— will be found a directly. The ratio — may be called the Index of Abmodality. The normal curve may preferably be employed even when & is not exactly equal to 0, nor /?2 exactly equal to 3, nor F exactly equal to 0. Use the normal curve when and 24 STATISTICAL METHODS. also the skewness (p. 30) should be less than twice the value .67449 4~. V 2n To determine the closeness of fit of a theoreti- cal polygon to the observed polygon. Find for each class the difference (<^) between the theoretical value (y} and the observed frequency (/). Divide the square of this difference in each case by y. The square root of the sum of the /~fl~2 quotients is the index of closeness of fit (J). Or, J= y I—- The probability (P:l) that the observed distribution is truly represented by the theoretical polygon may be calculated from the following formula, to use which the number of classes (A) must be odd or must be made odd by the addition of a class with 0 frequency. This is the method of Pearson, 1900&. To determine the probability of a given dis- tribution being normal. Having found, in units of the standard deviation, the deviation (7) of the inner limiting value (L) of each class from the average, look up the corresponding class-index a from Table IV. Or, better, find a directly for each class by dividing the half of the total num- ber of variates minus all those lying beyond the inner limit- ing value of the class in question by the half of the total I xf number of variates; or, in a formula, -p, where Jf0x/ means $n add all the frequencies from the median value to £, and n is the number of variates. Next find for each class the sum of A+a%. This should equal L. The difference is the actual discrepancy. The probable discrepancy should next be calculated for all but the extreme values. It is calculated by use of the formula THE CLASSES OF FREQUENCY POLYGONS. where the value of z corresponding to % is got from Table II I, or from the formula The ratio of actual to probable discrepancy is next to be calculated for each class. The probable limit (P.L.) of the ratios varies with the number (A) of ratios found, according to the following table : Ai P.L. A\ P.L.

The probable range of abscissae (2xt) of a normal dis- tribution, or that beyond which the theoretical frequency (y) is less than 1, varies with the number of variates (n) as well as with a, in accordance with the following formula derived by the transposition of y= by putting y=l: 2^=2*7 Example.

In studying correlation one (either one) of the characters is regarded as subject and the other as relative. A correlation table is then arranged as in the example on page 43, which gives data for determining the correlation between the num- ber of Miillerian glands on the right (subject) and left (rela- tive) legs of male swine. The selected subject class is called the type; the corresponding distribution of the relative mag- nitudes is called the array. METHODS OP DETERMINING COEFFICIENT OF CORRELATION. Gallon's graphic method. On co-ordinate paper draw perpendicular axes JTand T\ locate a series of points from the pairs of indices of abmodality of the relative and sub- ject corresponding to each subject class. The indices of the subjects are laid off as abscissae ; the indices of the relatives as ordinates, regarding signs. Get another set of points by mak- ing a second correlation table, regarding character B as subject and character A as relative. Then draw a straight line through these points so as to divide the region occupied by them into halves. The tangent of the angle made by the last line with the horizontal axis XX (any distance ypt divided by xp) is the index of correlation. A more precise method is given by Pearson as follows: Sum of products (deviation subj. class X deviation each iissoc. rel. class X no. of cases in both) total no. oFludivs. X Stand.

Even qualities that do not lend themselves to a quanti- tative expression may be expressed in a roughly quantitative fashion. The fundamental assumption is made that the frequencies would obey the normal law of frequency more or less closely, provided a quantitative scale could be found. This assumption will not, in most biological data, lead us far astray. Divide the data into three classes (e.g., in eye-color we may have black, brown and gray, and blue), and let the frequency of these classes be n,, n2, n3, in which rat and n3 are each less than %n, so that n2 contains the median. Let Llt L.+ be the (unknown) distances of the mean from the two boundaries of n2. Call Li/a=ht and Ls/a=/i3, then n, — n.2 — n , •AT'-"1* r 7T "0 and 48 STATISTICAL METHODS. Now the left-hand side in these equations is known ; it is \a of Table IV. From this table the right-hand value of the FIG. 11. equations is found; it is the entry corresponding to the argu- ment Ja. Thus /ij and 7t3 I = — J are found, and hence L^/a and Lz/a and the entire range — of the middle class, in terms of a, is known. Call the range in absolute units I. Then Z=Z/3 + I/1 and I/ 'a is known and for a second series I/ a* can be similarly determined. Hence a/a', the ratio of the variabilities of the two series, is determined. Again, since LJa and — — -1 are known, ^/(Z/g + Z/j) is known, and this gives us the ratio in which the mean divides the true range of the central class. (Pearson and Lee, 1900.) The foregoing method may sometimes be advantageously employed where the data are quantitative. In this case the numerical value of I is known. (Macdonell, 1902.) Consequently \ 4- h2 = is known and hence -=J — r2 "-i ~\~n3 , the standard deviation, is found. Since L, = h^ = the distance of the mean from the left-hand boundary of n2, the position of the mean is known.

Pearson (1900C) has ingeniously discovered a method of ex- pressing correlation quantitatively when the variables cannot be so expressed, as, for example, in the case of effectiveness of vaccination. Strictly, this method assumes normal vari- ation in variables, but it can be employed generally, in default of a better method, with fairly accurate results. The prime requisite is that the qualities to be compared shall be separable into two grades, an upper and a lower. For example, in the case of the result of vaccination: on the one hand, either presence or absence of a scar; on the other, either recovery or death. As either of the second pair may occur with either of the first pair, four classes, a, b, c, d, will be formed altogether and a correlation surface like the following may be made: a b a + b c d c + d a + c b + d n The axes y, — y and x1 — x probably do not coincide with the axes y and 2 -passing through the "origin" of the correlation 50 STATISTICAL METHODS. surface, but may be regarded as situated from those axes at the respective distances h and k. These values may be found from the formulae _e_tlf TT •/() a, b, c, and d being known, h and k are found from Table IV. Then and -= - V27T V27T of which the values may be looked up in Table III, or, better, their product may be calculated by logarithms as follows: Find also log hk, h2, and k2. To find r solve the following equation to as many terms as may be necessary: (/i4 - 67i2 + 3) (A;4 - GF + 3)r5 +-_Lhk(h*- lOh2 + "15) (k4 - lOfc2 + 15)r6 + etc. This gives us a numerical equation of the nth degree which can be solved by ordinary algebraic methods, using Sturm's functions and Horner's method. Or it can be solved by successive approximations as follows: The first approxima- tion is made by neglecting all powers of r above the second and solving the quadratic (remembering, that if ax2 + bx + c = 0, CORRELATED VARIABILITY. 51 n I , and taking the positive root. Substi- tute this value in the whole equation to the 4th power for /(r), and in the first derivative of the same equation for /'(r) (remembering that the first derivative of /(#) is obtained by multiplying each term in /(x) by the exponent of x in that term and diminishing the exponent of x by 1). The correc- tion 7774 should be added to the value of r used in substi- f (r) tuting. Repeat this process as often as the correction affects the fourth place of decimals, and go to r5 if necessary. The probable error of r as thus determined is found as follows: First calculate the relations &= — '- fr — rh and /?2 = — ^=. Also find V 1— r2 7= f le 2^«/0 and ^2= — 7= from Table IV.

In using the foregoing formula, it must be noted that "a is the quadrant in which the mean falls, so that h and k are both positive." In other words, a + c > b + d and a + b > c + d. (Pearson, J00C.)

SPURIOUS CORRELATION IN INDICES.

U3 — c, r0= " " " SDurious correlation. CORRELATED VARIABILITY. 55 The precise method of using r0 in modifying any determi- nation of r is uncertain. Pearson recommends using r — r0 as the true measure of " organic correlation" in the case of indices. HEREDITY. Heredity is a certain degree of correlation between the abmodality of parent and offspring. The statistical laws of heredity deal not with relations between one descendant and its parent or parents, but only with mean progeny of parents. Any group of selected parents is called a parentage, the progeny of a parentage is called a fraternity. Three categories of inheritance have long been recognized (Galton, 1888, p. 12). These are: (1) blending heritage illus- trated by stature in man; (2) alternative heritage, illustrated by human eye-color; and (3) mixed heritage, illustrated by the piebald condition of the progeny of mice of different colors. The immediately following statistical laws of inherit- ance hold especially for blending heritage. In miiparental inheritance, as in budding or asexual generation, heredity of any character is measured by the coef- ficient of correlation between the abmodality in a parentage and the abmodality of the corresponding fraternity. More strictly, since the variability of the character in the second generation, . Variability independent of sexual reproduction: Warren, '99, '02; Pearson and others, '01', pp. 359-362.

In the example, the data of which are given on p. 26, the frequency between the limits is given in % column. The — of G each limit (as an inner class limit) is found and the entries in Table IV corresponding to the limits are taken. Each such entry is subtracted from 0.50000, *Js multiplied by 100, and from the product is subtracted the total theoretical percentage of variates lying between the outer limit of the class and the corresponding extremity of the half curve. This gives the theoretical frequency of the class in question. The closeness of agreement of the last column with the "Percent." column indicates the closeness of the observed frequency to the theoretical. V. Table of log T functions of p. This table will enable one to solve the equations for yQ given on page 32. The table gives the logarithms of the values of F functions only within the range p — 1 to 2. As all values of the func- tion within these limits are less than 1, the mantissa of the logarithms is — 1; but it is given in the table as 10 — 1 = 9, as is usually done in logarithmic tables. Supposing the quantity of which we wish to find the value reduced to the form r(4.273). The value cannot be found directly because the value of p is larger than the numbers in the table (1 to 2). The solution is made by aid of the equation r(p + l)=pF(p), thus: log r(1.273) = 9.955185 log 1.273 =0.104828 log T(3.273) = 0.060013 log 2.273 =0.356599 log r(3.273) = 0.416612 log 3.273 =0.514946 log T(4. 273) = 0.931558 or, more briefly, log r(1.273) = 9.955185 log 1.273 = .104828 log 2.273 = .356599 log 3.273 = .514946 log T(4.273) = 0.931558 = log 8.542 EXPLANATION OF TABLES. 107 VI. Table of reduction from the common to the metric system. This is given first for whole inches from 1 to 99 excepting even tens, which may be got from the first line of figures by shifting the decimal point one place to the right. The table may be used for huudredths of an inch by shifting the decimal point two places to the left. Other fractious than decimals are given in the lower tables. . VII. Table of minutes and seconds of arc in decimals of a degree. This table will be found of use in the fitting of curves of Type IV (p. 33). VIII. First to sixth powers of integers from 1 to 3O. This table is useful in calculating moments. IX. Table of the probable errors of the coeffi- cient of correlation for various numbers of ob- servations or variates (n) and for various values of r. The probable error of the coefficient of correlation , . 0.6745(1 -r2) , , . , ^ being — -, a table for the varying values of n and r Vn is easily constructed, and for large values of n is accurate with interpolation by inspection to two significant figures, which are all that are required. X. Squares, cubes, square roots, and recip- rocals of numbers from 1 to 1O54. The use of this table can be extended by using the principle that if any number be multiplied by n, its square is multiplied by n2, its cube by n3, and its reciprocal by — . XI. Logarithms of numbers to six places. The following explanation of the use of the logarithmic tables is taken from Searles' Field Engineering, pp. 257-263 [ed. 1887]. The logarithm of a number consists of two parts, a whole number, called the characteristic, and a decimal, called the mantissa. All numbers which consist of the same figures standing in the same order have the same man- tissa, regardless of the position of the decimal point in the number, or of the number of ciphers which precede or follow the significant figures of the number. The value of the char- acteristic depends entirely on the position of the decimal point 108 STATISTICAL METHODS. in the number. It is always one less than the number of figures in the number to the left of the decimal point. The value is therefore diminished by one every time the decimal point of the number is removed one place to the left, and vice versa. Thus Number. Logarithm. 13840. 4.141136 1384.0 3.141136 138.40 2.141136 13.84 1.141136 1.384 0.141136 .1384 —1.141136 .01384 —2.141136 .001384 —3.141136 etc. etc. The mantissa is always positive even when the characteristic is negative. We may avoid the use of a negative characteristic by arbitrarily adding ID, which may be neglected at the closf of the calculation. By this rule we have Number. Logarithm. 1.384 0.141136 .1384 9.141136 .01384 8.141136 .001384 7.141136 etc, etc. No confusion need arise from this method in finding a number from its logarithm; for although the logarithm 6.141136 repre- sents either the number 1,384,000, or the decimal .0001384, yet these are so diverse in their values that we can never be uncer- tain in a given problem which to adopt. TABLE XI, contains the mantissas of logarithms, car- ried to six places of decimals, for numbers between 1 and 9999, inclusive. The first three figures of a number are given in the first column, the fourth at the top of the other columns. The first two figures of the mantissa are given only in the second column, but these are understood to apply to the remaining four figures in either column following, which are comprised between the same horizontal lines with the two. If a number (after cutting off the ciphers at either end) con- sists of not more than four figures, the mantissa may be taken direct from the table ; but by interpolation the logarithm of a number having six figures may be obtained. The last column contains the average difference of consecutive logarithms on EXPLANATION OF TABLES. 109 the same line, but for a given case the difference needs to be verified by actual subtraction, at least so far as the last figure is concerned. The lower part of the page contains a complete list of differences, with their multiples divided by 10. To find the logarithm of a number having six figures :— Take out the mantissa for the four superior places directly from the table, and find the difference between this mantissa and the next greater in the table. Add to the man- tissa taken out the quantity found in the table of proportional parts, opposite the difference, and in the column headed by the fifth figure of the number; also add ^ the quantity in the col- umn headed by the sixth figure. The sum is the mantissa required, to which must be prefixed a decimal point and the proper characteristic. Example.— Find the log of 23.4275. For 2342 mantissa is 369587 " diff. 185 col. 7 129.5 " " " " 5 9.2 Am. For 23.4275 log is 1.369726 The decimals of the corrections are added together to deter- mine the nearest value of the sixth figure of the mantissa. To find the number corresponding to a given logarithm. — If the given mantissa is not in the table find the one next less, and take out the four figures corresponding to it ; divide the difference between the two mantissas by the tabu- lar difference in that part of the table, and annex the figures of the quotient to the four figures already taken out. Finally, place the decimal point according to the rule for characteristics, prefixing or annexing ciphers if necessary. The division re- quired is facilitated by the table of proportional parts, \vhich furnishes by inspection the figures of the quotient. Example. — Find the number of which the logarithm is 8.263927 8.263927 First 4 figures 1836 from 263873 Diff. 540 Tabular diff. =236 . - . 5th fig. =2 47. 2 6.80 6th fig. = 3 7.08 Ans. No. = .0183623 or 183,623,000. 110 STATISTICAL METHODS. The number derived from a six-place logarithm is not reliable beyond the sixth figure. At the end of Table XI is a small table of logarithms of numbers from 1 to 100, with the characteristic prefixed, for easy reference when the given number does not -exceed two digits. But the same mantissas may be found in the larger table. TABLE XII. — The logarithmic sine, tangent, etc., of an arc is the logarithm of the natural sine, tangent, etc., of the same arc, but with 10 added to the characteristic to avoid negatives. This table gives log sines, tangents, cosines, and cotangents for every minute of the quadrant. With the number of degrees at the left side of the page are to be read the minutes in the left-hand column; with the degrees on the right-hand side are to be read the minutes in the right-hand column. When the degrees appear at the top of the page the top headings must be observed, when at the bottom those at the bottom. Since the values found for arcs in the first quad- rant are duplicated in the second, the degrees are given from 0° to 180°. The differences in the logarithms due to a change of one second in the arc are given in adjoining columns. To find the log. sin, cos, tan, or cot of a given arc. : Take out from the proper column of the table the log- arithm corresponding to the given number of degrees and minutes. If there be any seconds multiply them by the ad- joining tabular difference, and apply their product as a cor- rection to the logarithm already taken out. The correction is to be added if the logarithms of the table are increasing with the angle, or subtracted if they are decreasing as the angle in- creases. In the first quadrant the log sines and tangents in- crease, and the log. cosines and cotangents decrease as the angle increases. JSxample.—Yind the log sin of 9° 28' 20".
