The researcher is likely performing factor analysis, which involves analyzing the intercorrelations among a set of variables to identify underlying factors or dimensions that explain the pattern of correlations. This is a common preliminary step in developing standardized tests or measures. Multiple regression involves predicting a criterion variable from one or more predictor variables, partial correlation determines the relationship between two variables while controlling for the effects of one or more other variables, and criterion validity involves examining the relationship between a measure and an external criterion variable.
