By this process both extremes had been elimi nated; that is, the slow girls had been laid off and the fast girls had modified their pace to suit the retarded pace °f production. Thus, all the girls who were left tended t0 accomplish about the same amount of work per day. These conditions made the production of these girls an unfair indication of their relative ability under normal conditions, and consequently made it impossible to ob tain a fair estimate of the tests on the basis of produc tion. This was especially true in the case of the paper shot shell inspectors where the lowest correlations were found. In fact, the average difference in the rate of pro duction between these girls was only two and two-tenths Per cent of the average day’s work, as contrasted with an average of twenty-seven per cent in the case of shell in spectors. The average difference for the four groups was as follows: Per Cent. 1. Shell inspectors 27.7 2. Bullet inspectors 18.7 3. Cartridge inspectors 6.9 4. P. S.
