      1. The Pearson Correlation Coefficient. Correlation. In statistics, the word "correlation" has a very specific meaning. Statistical 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, and vice versa.

      Pearson’s Product-Moment Correlation Coefficient. Also called Correlation Coefficient or ‘ r ’. This is a more precise tool. In summary it is a measure of the tendency of data to lie on a straight line. The value of ‘r’ ranges from -1 to 1 i.e. -1 ≤ r ≤ 1. Following are examples of scatterplots:

      Pearson’s correlation coefficient. Measures the strength of the linear relationship between two variables. The correlation between two variables reflects the degree to which the variables are related. The most common measure of correlation is the Pearson Product Moment Correlation (called Pearson's correlation for short).
