Question

Question 24 (4 points) If the correlation coefficient r is equal to 0.57, find the coefficient of nondetermination. 1) 0.68 2) 0.75 3) 0.45 O4) 0.32

Answer 1

Solution:

We are given

Correlation coefficient = r = 0.57

So, we have

Coefficient of determination = r² = 0.57^2 = 0.3249

Coefficient of determination = 0.32

Coefficient of non-determination = 1 - Coefficient of determination

Coefficient of non-determination = 1 - 0.32

Coefficient of non-determination = 0.68

Answer: 0.68
