Quizplus · Accepted Answer

A strong relationship between two variables can indeed exist with a low correlation coefficient if the relationship is not linear or if the variables are truncated. Correlation coefficients measure the strength and direction of a linear relationship between two variables. Non-linear relationships or truncated data can distort or reduce the apparent correlation, even if the variables are strongly related in some form.
