Pearson product-moment correlation coefficient 1 Pearson product-moment correlation coefficient In statistics, the Pearson product-moment correlation coefficient (sometimes referred to as the PMCC, and typically denoted by r) is a measure of the correlation (linear dependence) between two variables X ...
A correlation coefficient is used in statistics to describe a pattern or relationship between two variables. Anegative correlationdescribes the extent to which two variables move in opposite directions. An increase in X is associated with a decrease in Y for two variables, X and Y. A negative c...
The most common correlation coefficient is thePearson Correlation Coefficient. It’s used to test for linear relationships between data. In AP stats or elementary stats, the Pearson is likely the only one you’ll be working with. However, you may come across others, depending upon the type of...
