# Question: Poindexter finds r 80 when correlating number of hours

Poindexter finds r = -.80 when correlating number of hours studied and number of errors made on a statistics test. He also finds r = + .40 between speed of taking the test and number of errors on the test. He concludes that hours studied forms twice as strong a relationship and is therefore twice as important as the speed of taking the test.

(a) Why is he correct or incorrect?

(b) Compare these relationships and draw the correct conclusion.
