Question

The Pearson correlation coefficient would indicate that the data set below has a(n):

A. strong positive relationship.

B. strong negative relationship.

C. undefined relationship because the line is horizontal.

D. relationship that is near zero because no linear relationship exists.

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.
