What does factor analysis primarily determine in test construction?
Understand the Problem
The question is asking what factor analysis aims to determine in the context of constructing a test. It requires an understanding of the principles of factor analysis and its role in test evaluation.
Answer
Determines underlying dimensions or latent structures.
Factor analysis primarily determines underlying dimensions or latent structures in test construction by reducing many variables to a smaller number of factors.
Answer for screen readers
Factor analysis primarily determines underlying dimensions or latent structures in test construction by reducing many variables to a smaller number of factors.
More Information
In test construction, factor analysis is essential for understanding the underlying constructs measured by the test items. This helps in ensuring the test measures what it intends to, improving both its reliability and validity.
Tips
A common mistake is to assume factor analysis can identify and explain causation between variables; it only identifies correlations.
