Question

For a data set of chest sizes (distance around chest in inches) and weights (pounds) of

eleven

anesthetized bears that were measured, the linear correlation coefficient is

r=0.847.

Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation

view the table of critical values of r.

What are the critical values of r?

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
