Question

If there is a very strong correlation between two variables, then the correlation coefficient must be
A. any value greater than 1.
B. much smaller than 0, if the correlation is negative.
C. much larger than 0, regardless of whether the correlation is negative or positive.
D. None of these.

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.
