Question

complete the statement. the range of values for the correlation coefficient is from to .

Explanation:

Step1: Recall correlation coefficient range

The correlation coefficient, denoted as $r$, measures the strength and direction of a linear relationship between two variables. Its range is well - defined.

Step2: State the range

The value of $r$ ranges from $- 1$ to $1$. A value of $r = - 1$ indicates a perfect negative linear relationship, $r = 1$ indicates a perfect positive linear relationship, and $r = 0$ indicates no linear relationship.

Answer:

$-1$; $1$
