The value of r indicates the negative correlation.

<h2>Given </h2>

Rikki decided to collect data to determine if a runner's time and speed are correlated.

She determined the data to have a correlation coefficient of -0. 5.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.

She determined the data to have a correlation coefficient of -0. 5.

Here, the coefficient is negative which is -0.5.

This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.

This relation is negative because the correlation coefficient is negative.

Hence, The value of r indicates the negative correlation.
