Examination of the annual turnover figures of an assortment of products (individually in the case of comparable products, in terms of money in the case of others) often reveals that these figures follow a curve which is a reasonable approximation of a lognormal distribution. The cumulative distribution, plotted on a logarithmic scale, will then constitute a straight line. For example, Fig. 10 illustrates the conversion of the lognormal, skew, distribution of the annual turnover figures D, through the different transformations and transitional stages, into a straight line for the cumulative distribution.
