http://statisticslectures.com/topics/pearsonr/ WebPearson s r measures the strength of the linear relationship between two variables. Pearson s r is always between -1 and 1. Here is a perfect positive relationship. r is equal to 1.0: Figure 2. Here is a perfect negative relationship. r is equal to -1.0: Figure 3. Here is an example of data that has no relationship. r is somewhere close to 0.0:
WebThe most familiar measure of dependence between two quantities is the Pearson product-moment correlation coefficient (PPMCC), or "Pearson's correlation coefficient", commonly called simply "the correlation coefficient". It is obtained by taking the ratio of the covariance of the two variables in question of our numerical dataset, normalized to ... The correlation coefficient ranges from −1 to 1. An absolute value of exactly 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line. The correlation sign is determined by the regression slope: a value of +1 implies that all data points lie on a line for which Y increases as X increases, and vice versa for −1. A value of 0 implies th…
