1. PEARSON: Calculates r, the Pearson product-moment correlation coefficient of a dataset

2. Looking at the actual formula of the Pearson product-moment Correlation coefficient would probably give you a headache.

3. The point-Biserial correlation is a special case of the product -moment correlation in which one variable is

4. The point Biserial correlation coefficient lies in the range [-1, 1] and its interpretation is very similar to Pearson’s Product Moment Correlation Coefficient, i.e., stronger higher the value

5. In statistics, the Pearson Correlation coefficient (PCC, pronounced / ˈ p ɪər s ən /), also referred to as Pearson's r, the Pearson product-moment Correlation coefficient (PPMCC), or the bivariate Correlation, is a measure of linear Correlation between two sets of data
