Fig. 155. Chart Showing What Percentage of the Wage Earners in Different Portions of the United States Receive More than any Specified Amount of Earnings up to Twenty-Five Dollars per Week
Here the scales are correctly arranged so that the two zeros appear at the lower left-hand comer. The plotting of these curves on a "more than" basis causes curves which show the largest earnings to appear in their proper position toward the top of the chart. Plotting of cumulative frequency curves on a "more than" basis is usually desirable, since it reduces the chances for confusion to ths reader. This chart could have been improved if the words "more than" and an arrow had been placed at the lower lefthand corner on the general scheme of Fig. 158
