Q. 18 - Elementary Statistics

Question

A value of $r$ close to -----suggests at most a weak linear relationship between the variables.

Step-by-Step Solution

Answer

A value of $r$ close to $0$ suggests at most a weak linear relationship between the variables.

Step 1: Given Information

To determine the blank in the given statement.

Step 2: Explanation

The orientation of the linear association between $x$ and $y$ can be deduced from the sign of the linear correlation coefficient. The linear link is strong when r (the correlation coefficient) is around $1$ or $-1$; it is weak when r is near $0$.
