WebSome scatterplots have curved patterns. Such scatterplots are said to show nonlinear association between the two variables. The correlation coefficient does not reflect nonlinear relationships between variables, only linear ones. For example, even if the association is quite strong, if it is nonlinear, the correlation coefficient r can be small or zero.
