A reseаrcher wаnts tо meаsure the effectiveness оf a 3-mоnth high protein meal plan on the performance of 14 runners. The runners run two different lengths of 3 miles: one prior to starting the 3-month high protein meal plan and one after eating the high protein meal plan for 3 months. The difference in run times between the run prior to the diet and the run after the diet was recorded for all 14 runners. The data obtained should be analyzed using which method?
