The first step in the calculation of the Pearson product-moment correlation coefficient is to:
a. determine the z score for each score on each variable.
b. determine the cross-products of the z scores.
c. multiply the z score for variable X by the z score for variable Y.
d. divide the cross-products by N.
Question 2
To calculate the coefficient of determination, we:
a. square the correlation coefficient.
b. take the square root of the correlation coefficient.
c. multiply the correlation coefficient by 2
d. divide the correlation coefficient by 2
