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.
