XV.—BINOMIAL DISTRIBUTION AND NORMAL CURVE. 303 Y, produces a proportionate alteration in the area of the curve, e.g. doubling 7, doubles every ordinate 7, and therefore doubles the area: (2) any alteration in o produces a proportionate alteration in the area, for the values of y, are the same for the same values of z/o, and therefore doubling o doubles the distance of every ordinate from the mean, and consequently doubles the area. The area of the curve, or the number of observations represented, is therefore proportional to 7,0, or we must have N=axy,o where a is a numerical constant. The value of a may be found approximately by taking 7, and o both equal to unity, calculating the values of the ordinates y, for equidistant values of z, and taking the area, or number of observations X, as given by the sum of the ordinates multiplied by the interval. 11. The table below gives the values of y for values of x proceeding by fifths of a unit ; the values are, of course, the same for positive and negative values of z. For the whole curve the sum of the ordinates will be found to be 1253318, the interval being 0'2 units; the area is therefore, approximately, 2:50664, SZ Ordinates of the Curve y=e¢ 2.

The value is more than sufficiently accurate for practical purposes, for the exact value is ~/2r=2506627..... The proof of this value cannot be given here, but it may be deduced from an important approximate expression for the factorials of large numbers, due to James a in Zz. Y. ,
