Which of these correlation numbers shows the strongest relationship? +.46 +.32 - 0.41 - 0.68

Answer: - 0.068

Explanation:

A familiar correlation number of R² denotes the degree of correlation between measured data and the curve of best fir

R² = 1 denotes a perfect fit, so that

R = + 1, or R = - 1 denotes a perfect fit.

R² = 0 denotes no correlation.

To compare the given correlation numbers, we should consider their absolute values. In decreasing order, they are

-0068 = > 0.68

0.46 = > 0.46

-0.041 = > 0.41

0.32 = > 0.32
