Factor analysis is a statistical technique used for identifying correlations among variables, which helps in identifying clusters of related variables. It is commonly used in the field of psychology and education to analyze test scores and identify underlying factors or dimensions that are being measured by the items on the test. Factors can be interpreted and named based on the pattern of correlations among the items that load onto each factor. Therefore, factor analysis is the best choice for identifying clusters of related test items.
