Question: Calculate the correlation coefficient for the data provided by completing these three steps:
a. Calculate deviation scores, multiply the deviations for each individual, and sum all products. This is the numerator of the correlation coefficient equation.
b. Calculate the sum of squares for each variable. Then compute the square root of the product of the sums of squares. This is the denominator of the correlation coefficient equation.
c. Divide the numerator by the denominator to compute the coefficient, r.
