In Developing a Multiple Aptitude Test, the Test Developers Wanted

In developing a multiple aptitude test, the test developers wanted to assure that the various subtests do not correlate strongly with one another, thus assuring the integrity of each subtest. They conduct a number of intercorrelations among subtests. This type of validity is called:

A) experimental design validity.
B) factor analysis validity.
C) convergent validity.
D) criterion-related validity.
E) predictive validity.
