# Factor Analysis Question - Covariance and Correlation matrix

September 13, 2010 5:26 PM Subscribe

In exploratory factor analysis, why would I want to do a factor analysis on the covariance matrix rather than the correlation matrix? I did some tests, and they clearly assess different things, but I'm unable to find an explanation of the conditions in which you would prefer to use the covariance matrix over the more commonly used correlation matrix.
