FREQUENCY CURVES

In Fig. 156 we have cumulative frequency curves applied to a comparison of wages in different departments of a corporation.

A chart of this kind is of great utility in making a study of wages. It may be noticed, for instance, in the curve for laborers, that there is a very decided change in the shape of the curve at about $9.00 per week. Only 62 per cent of these laborers make more than $9.00 per week and but 80 per cent of them get more than $5.00 per
