Answer to Question 2

An eigenvalue is a measure of the ratio of the variance explained by a specific factor to that by the average factor. Therefore the sum of the eigenvalues for a factor analysis solution will equal the original number of variables. A typical approach is for factors with eigenvalues less than 1 to be discarded; those with eigenvalues not too much greater than 1 to be considered suspect; and those with large eigenvalues retained in the solution. How much greater than 1 an eigenvalue should be for a factor to be deemed acceptable is a judgment call.
