1. The Pearson Correlation Coefficient Correlation You've likely heard before about how two variables may be correlated. While we use this word in an informal sense, there is actually a very specific meaning of the term in statistics. Correlation means that, given two variables X and Y measured for each case in a sample, variation in X corresponds (or does not correspond) to variation in Y Pearson Correlation 1.
