Further information on the Pearson Product-Moment Correlation Coefficient is provided on Wikipedia. Pearson Product-Moment Correlation Coefficient. The Pearson product-moment correlation coefficient is a statistical measurement of the correlation (linear association) between two sets of values. The Pearson product-moment correlation coefficient for two sets of values, x and y, is given by the formula: where x and y are the sample means of the two arrays of values.
A correlation coefficient measures the degree (strength) of the relationship between two variables. The Pearson Correlation Coefficient measures the strength of the linear relationship between two variables. Two specific strengths are:
