Characteristics of the Battery
The entire battery requires approximately 2 l/2 hours to administer,
!
The longest test, Arithmetic Reasoning, takes about 25 minutes; the
shortest, Coding Speed (clerical aptitude), takes 7 minutes; most of the
t
others are lo-minute tests.
Reliability coefficients are presented in Table 1, and test intercorrc-
lations appear in Table 2. The intercorrelations are of intermediate
