# Pearson correlation coefficient: Gaussian data expected?

The Pearson correlation coefficient is sometimes referred to as a parametric statistic. Does this parametric nature imply that it is actually only applicable to data drawn from Gaussian distributions?

• Statistics are not "parametric" per se. What, then, would be the context in which you see correlation coefficients referred to as "parametric statistics"? – whuber Feb 17 '19 at 23:03
