Delegates will review advanced statistical techniques such as Factor analysis, logistic regression test, average variance extracted (AVE) and maximum variance shared (MVS) interpretation, two-way ANOVA, MANOVA and ANCOVA tests. Since X is a random variable it fluctuates around an average (mean) value E(0.7X) = 0.7E(X) = 0.7μ x So E(Y) = 4000 + 0.7 μ x Follows that the variance of Y given by [ 2 ] [( ) (4000 0.7 4000 0.7 ) 2] E Y μy E X − = + − − μx []2 [{}] [( ) (0.7( ) 0.49 ( ) 2] E Y μy − = E X μx − = E X −μx so Var(y) = 0.49Var(X) Since standard deviation is square root of variance s.d.

In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated..
