Suppose the following summary statistics are obtained from a large group of individuals:X =52.0, Sx= 8.7, Y =147.3, Sy = 16.9. Dorothy receives an Xscore of 52. What is her predicted Y score if r = o?

• statistics -

I assume that X and Y stand for the group means, and S indicates Standard Deviation.

However, if r = 0, there is no predictability from one variable to the other.
