KMO (Kaiser-Meyer-Olkin Test

Answer 1

measure of sampling adequacy; tells you if the sample adequately represents the population; needs to be >.5, the closer to 1 the better

Question 2

Bartlett’s Test of Sphericity

Answer 2

Test the null hypothesis that the variables are uncorrelated in the population; FA cannot be done if this assumption is true (ie. there is no correlation); significant at >.05

Question 3

Fisher’s P-Test

Answer 3

tells you whether the relationship is statistically significant; <.05

Question 4

Answer 4

most often used; determine the stability behavior of a system around the fixed point; > 1 is desired, we look at all components/factors adn only select those w/ eigenvalue over 1
