Solution
Generally, correlation coefficients range between -1.00 to +1.00. According to the rule of correlation coefficients, the strongest correlation is considered when the value is closest to +1 (positive correlation) or -1 (negative correlation).
Given the r-values below
0.45, 0.32, 0.50, 0.62?
The highest is 0.62
Thus, the r-value that represents the strongest correlation is 0.62
