Question

Name three methods for obtaining a solution in a factor analysis (NOT rotation methods)

Name two methods for rotating loadings in a factor analysis

If you run a factor analysis on a correlation matrix, the eigenvalues sum to what number

When would you want to run a principal components analysis on a covariance matrix?

The product of the eigenvalues of the covariance matrix is equal to the

……………………………………….. When an eigenvalue is zero, it indicates that the covariance matrix is

……………………………………………………………………………………..

1.) The three methods for obtaining a solution in a factor analysis are :

Principal Component Analysis

Common Factor Analysis

Image Factoring

2.) Two methods for rotating loadings in factor analysis are :

Oblique rotations

Orthogonal rotations

3.) The sum of all eigenvalues = Total number of Variables

5.) The product of the eigenvalues of the covariance matrix is equal to the determinant of the matrix.

6.) when the eigenvalue is zero, it indicates that the covariance matrix is Singular and consequently not invertible.
