Question

what does the r value have to be close to for the relationship to be stronger? 10, -10 1, -1 0 2, -2 rewatch submit

Explanation:

The correlation coefficient \( r \) measures the strength and direction of a linear relationship between two variables. The value of \( r \) ranges from \(- 1\) to \(1\). When \( r = 1\), there is a perfect positive linear relationship, and when \( r=-1\), there is a perfect negative linear relationship. As \( r \) gets closer to \(1\) or \(-1\), the linear relationship becomes stronger. A value of \( r = 0\) indicates no linear relationship. Values like \(10,-10,2,-2\) are outside the valid range (\(-1\leq r\leq1\)) for the correlation coefficient.

Answer:

1, -1
