123 THEORY OF STATISTICS. distribution, is 2:99. As further illustrations of the closeness with which the relation may be expected to hold in different cases, we give below the results for the distributions of pauperism in the unions of England and Wales in the years 1850, 1860, 1870, 1881, and 1891 (the last being the illustration taken above), and also the results for the distribution of barometer heights at Southampton (Table XI., Chap. VI. § 14), and similar distribu- tions at four other stations. Comparison of the Approximate and True Modes in the Case of Ive Dis- tributions of Pauperism (Percentages of the Population in receipt of Relief) in the Unions of England and Wales. (Yule, Jour. Roy.

In all the other years the difference between the true and approximate values of the mode is hardly greater than the alteration that might be caused in the true mode itself by slight variations in the method of fitting the curve to the actual distribution. Similar remarks apply to the second series of illus- trations ; the true and approximate values are extremely close, except in the case of Dundee and Glasgow, where the divergence reaches two-hundredths of an inch. 21. Summing up the preceding paragraphs, we may say that the mean is the form of average to use for all general purposes; 6 oA
