Pearson's product moment correlation in r
WebApr 11, 2024 · The correlation coefficient for a perfectly negative correlation is -1. 2. Negative Correlation (-1≤ r <0) A negative correlation is any inverse correlation where an increase in the value of X is associated with a decrease in the value of Y. For a negative correlation, Pearson’s r is less than 0 and greater than or equal to -1. WebBartlett, R. F. (1993).

WebEstimates the Pearson product-moment correlation coefficient matrix of the variables given by the input matrix, where rows are the variables and columns are the observations. Note The correlation coefficient matrix R is computed using the covariance matrix C as given by R_ {ij} = \frac { C_ {ij} } { \sqrt { C_ {ii} * C_ {jj} } } Rij = Cii∗CjjCij WebThe formula for computing Pearson's ρ (population product-moment correlation coefficient, rho) is as follows [1]: where cov(X,Y) is the covariance of the variables X and Y and σ X (sigma X) is the population standard deviation of X, and σ Y of Y. Mathematically, it is defined as the quality of least squares fitting to the original data.
WebFeb 9, 2024 · The data of this study were analyzed statistically with Pearson Product Moment Correlation.
