Question 330

A neuropsychologist measures the relationship between hours of sleep deprivation and performance on a cognitive processing task across four different experimental groups, obtaining the following correlation coefficients (rrr):

  • Group 1: r=−0.91r = -0.91r=−0.91
  • Group 2: r=−0.15r = -0.15r=−0.15
  • Group 3: r=+0.08r = +0.08r=+0.08
  • Group 4: r=+0.87r = +0.87r=+0.87

Which of these correlation coefficients indicates the weakest relationship between sleep deprivation and cognitive performance?

A

−0.91-0.91−0.91

B

−0.15-0.15−0.15

C

+0.08+0.08+0.08

D

+0.87+0.87+0.87
