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
