Answer: 0.62
Explanation:
We know that when the r value is closer to the absolute value of 1 i.e. either 1 or -1, then it represents that there is a stronger correlation.
The given r-values : 0.62,0.50,0.32,0.45
From all the given correlation coefficient , the r value which closest to the absolute value of 1 is 0.62.
Therefore, the r-value that represents the strongest correlation = 0.62
