VIL.—THE FREQUENCY-DISTRIBUTION. : TABLE IV. Showing the Annual Value and Number of Dwelling-houses in Great Britain assessed to Inhabited House Duty in 1885-6, (Cited from Jour, Roy. Stat.

This gives the mean frequencies per £10 interval tabulated in the third column of Table IV. The reduction is, however, impossible in the case of the last class, for we are only told the number of houses of £1000 annual value and upwards : the magnitude of the class is indefinite. Such an indefinite class is in many respects a great inconvenience, and should always be avoided in work not subject to the necessary limitations of official publications. The general rule that intervals should be equal must not be held to bar the analysis by smaller equal intervals of some portion of the range over which the frequency varies very rapidly. In Table XII, p. 98, for example, giving the numbers of deaths from diphtheria at successive ages, a five-year interval might be substituted with advantage for the irregular intervals after the fifth year of age, but it would still be desirable to give the numbers of deaths in each year for the first five years, so as to bring out the rapid rise to the maximum in the fourth year of life. 11. When the table has been completed, it is often convenient to represent the frequency-distribution by means of a diagram which conveys the general run of the observations to the eye better than a column of figures.
