Question

What is the Pearson's r correlation coefficient between two variables X and Y if their covariance is 150 and the standard deviation of X is 12 and the standard deviation of Y is 20?

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.
