Suppose the correlation coefficient between the SAT verbal s

Suppose the correlation coefficient between the SAT verbal score and IQ is r = +.50. What z score on the SAT verbal test do you predict for someone whose z score on IQ is +3.00? -2.00? 0.00? -1.00? +1.00? -0.50?

Solution

a) 3 * 0.50 = 1.5

b) -2 * 0.50 = -1

c) 0 * 0.50 = 0

d) -1 * 0.50 = -1/2

e) 1 * 0.50 = 1/2

f ) -0.50 * 0.50 = -0.25
