Question

If the correlation between two sets of scores is 0 and one had to predict the value of Y for any given value of X, the best prediction of Y would be ___.

a. bY
b. Y bar
c. 0
d. X bar

Answer 1

If the correlation between two sets of scores is 0, the best prediction of Y for any given value of X would be Y bar.

Step-by-step explanation:

In this case, if the correlation between two sets of scores is 0, it means there is no linear relationship between the variables X and Y. Therefore, the best prediction of Y for any given value of X would be using the mean or average of Y, which is represented by Y bar.
