WebNov 22, 2014 · The Pearson correlation coefficient measures the linear relationship between two datasets. Strictly speaking, Pearson's correlation requires that each dataset be normally distributed. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. Correlations of -1 or +1 imply an exact linear relationship. WebAssumptions. Continuous variables - The two variables are continuous (ratio or interval).; Outliers - The sample correlation value is sensitive to outliers. We check for outliers in the pair level, on the linear regression residuals, Linearity - a linear relationship between the two variables, the correlation is the effect size of the linearity.
