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. CORRELATION COEFFICIENTS. We've discussed how to summarize a single variable. The next question is how to summarize a pair of variables measured on the same observational unit. CORRELATION. DEFINITION. The Pearson Product-Moment Correlation Coefficient (r), or correlation coefficient for short is a measure of the degree of linear relationship between two. Correlation Coefficient L et's return to our example of skinfolds and body fat. The correlation coefficient (r) indicates the extent to which the pairs of numbers for these two. The squared correlation coefficient is also known as the coefficient of determination. It is one of the best means for evaluating the strength of a relationship. r = the Pearson product-moment correlation coefficient; T; r 2 = the coefficient of determination; T; the slope of the regression line; T; the Y intercept of the regression line; T. Correlation: Interpretations. While the coefficient of covariance has no upper and lower limits, the coefficient of correlation can vary from positive one (indicating a perfect.
