It is the ratio between the … See more It was developed by Karl Pearson from a related idea introduced by Francis Galton in the 1880s, and for which the mathematical formula was derived and published by Auguste Bravais in 1844. The naming of the coefficient is … See more The values of both the sample and population Pearson correlation coefficients are on or between −1 and 1. Correlations equal to +1 or −1 correspond to data points lying exactly on a line (in the case of the sample correlation), or to a bivariate distribution … See more Statistical inference based on Pearson's correlation coefficient often focuses on one of the following two aims: • One aim is to test the null hypothesis that the true correlation coefficient ρ is equal to 0, based on the value of the sample correlation … See more Existence The population Pearson correlation coefficient is defined in terms of moments, and therefore exists for any bivariate probability distribution for … See more Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean … See more 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 … See more The square of the sample correlation coefficient is typically denoted r and is a special case of the coefficient of determination. In this case, it estimates the fraction of the … See more
