If during the development of a multiple aptitude test, the test publisher finds a number of high correlations among several of their subtests, this could be an indication of:

A) high validity, as the test shows inter-test purity.
B) high reliability, as the tests are highly correlated with one another.
C) the need for further refinement of the test, as some of the subtests may be measuring similar factors.
D) low practicality because time could be saved by administering less tests.
E) none of these.

Multiple Aptitude Test

A test designed to measure a broad spectrum of abilities or intellectual capabilities in various domains, such as verbal, mathematical, and spatial skills.

High Correlations

This pertains to a significant relationship between two variables indicating that as one variable changes, the other does too, either in the same (positive correlation) or in the opposite direction (negative correlation).

Subtests

Specific sections or components of a larger test, each designed to measure a particular skill or knowledge area.
