Expert Solution
Step 1

Explanation:

Correlation coefficient:

Correlation coefficient shows the linear relationship between two variables and measures the direction and strength of a linear relationship.

The correlation coefficient always lies between -1 and 1

If the correlation coefficient ρ = 1, then there is a perfect positive linear relationship between the pair of variables.

If the correlation coefficient ρ = -1, then there is a perfect negative linear relationship between the pair of variables.

If the correlation coefficient ρ = 0, then there is no linear relationship between the pair of variables.

 

The correlation significant between the pair of variables will be weakest correlation, If correlation coefficient ρ is very close to zero.

Weakest correlation at, ρ < 0.01
