# What is the purpose of group differentiation when assessing for construct validity?

A) To determine whether a test can differentiate two different groups of people in a way predicted by theory

B) To determine if scores on a test are found to be uncorrelated to scores on another instrument measuring a different construct

C) To produce a statistical coefficient

D) None of the above

Group Differentiation

The process by which members of a group distinguish themselves from members of other groups through social, cultural, or physical markers.

Construct Validity

The extent to which a test may be said to accurately and thoroughly measure a particular construct or trait.

- Recognize the differences among content, criterion, and construct validity types.
- Describe the process and importance of item analysis in assessing construct validity.

Final Answer :

A

Explanation :

Group differentiation is used to determine whether a test can differentiate two different groups of people in a way predicted by theory. This is important for establishing construct validity because it tests whether the test actually measures what it is supposed to measure in a meaningful way.

Answer: D

None of the other options accurately describe the purpose of group differentiation in relation to construct validity. Group differentiation is not used to determine correlations with other instruments, nor is its purpose to produce a statistical coefficient on its own.
