Title: Low reliability of the variables reduces the correlation coefficient because A
Post by: Hog95 on Sep 18, 2014
Low reliability of the variables reduces the correlation coefficient because 
A)   The Z scores are less likely to follow a normal curve. 
B)   The cross-products of the Z scores are less likely to follow a normal curve. 
C)   It adds random noise to the computations.
D)   It reduces random influences that would otherwise add to the overall variance.
