Exam 18: Exploratory Factor Analysis

A top way of determining the number of factors to retain is generating a random set of cases that have a similar number of items to your target data set. You then compare the magnitude of eigen values in your random data set to the magnitude of eigen values in your real data set to see at what point the random data has larger values than the real data set. This technique is called _____.

Question 3

Correct Answer:

Verified

First off, theory and common sense should guide results. You should have a large enough sample size relative to number of items to provide stable results. You should use parallel analysis (along with common sense) to choose the number of factors to interpret. And you should use a rotation to improve interpretability. Items that do not load on factors or cross-load significantly on factors should be thrown out.
