■well in the tests were doing excellent work as assemblers 
a nd were making over three dollars a day. “They are 
far better than some boys we tried on that work before,” 
remarked the foreman, “and all but one of them stands 
U P to her work.” 
The standing of the girls in the test for the perception 
of odd shapes and sizes and their standing in the opinions 
°f their superiors agreed in every case but two. Ex 
pressed in terms of correlation, the agreement was plus 
•l' 1 - In the other tests the agreement was not so marked, 
but nevertheless there was a positive and significant cor 
respondence. The correlation for the combined manual 
dexterity tests was .52, while that for the hand dyna 
mometer was .34. 
The impersonal but nevertheless easily interpreted re 
sults of these tests may be illustrated by the following in 
stances: One girl’s record in the test for the perception of 
°dd shapes and sizes showed that she had been very slow 
an d made frequent mistakes. On her record card this 
showed simply as 5? 51587—4 (meaning test number fifty- 
ooo, done in eighty-seven seconds with four mistakes), 
the writer, although he had not given these tests and 
knew nothing about the girls in question, remarked to 
the foreman: 
This girl’s record shows that she had a very poor idea 
°f where the parts belonged.” 
"That’s exactly how her work was,” quickly responded 
the foreman. 
Hut on the basis of these tests,”—indicating the girl’s 
mcord in the tests for manual dexterity— “ she seems to 
had pretty nimble fingers.” 
Yes,” countered the foreman, “but her mind wasn’t 
aj fast as her hands.”
