Note: Inter-Rater Reliability of Scree Test and Mean Square Ratio Test of Number of Factors

The inter-rater reliability of Cattell's scree and Linn's mean square ratio test of the number of factors was studied. Sample correlation matrices were generated from a population correlation matrix by means of standard Monte Carlo procedures such that there were 100 samples based on each of 3 sample sizes. Each matrix was factored and the scree test and the mean square ratio test were each applied by five raters. For both tests, the inter-rater reliabilities were very low. These results suggest that inexperienced factor analysts should be wary of these tests of the number of factors.
