Question

A set of data has correlation coefficient r. For which value of r would the average magnitude of theresiduals be the smallest?

Answer 1

The correlation coefficient, denoted by r, is a measure of the strength of the straight-line or linear relationship between two variables. The correlation coefficient takes on values ranging between +1 and -1. 0 indicates no linear relationship.

So, from the options:

$-0.034\to0$

is the best choice
