Question

What does a correlation coefficient of 2 indicate?

There is a weak relationship between the two quantitative variables.
It indicates a calculation error, as the correlation coefficient cannot be 2.
There is a strong relationship between the two quantitative variables.
It indicates a non-linear relationship between the two quantitative variables.
There is no linear relationship between the two quantitative variables.

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.
