WebPearson correlation coefficient, also known as Pearson R, is a statistical test that estimates the strength between the different variables and their relationships. WebJan 6, 2024 · Pearson’s Correlation coefficient is represented as ‘r’, it measures how strong is the linear association between two continuous variables using the formula: Values of Pearson’s Correlation are: Value of ‘r’ ranges from ‘-1’ to ‘+1’. Value ‘0’ specifies that there is no relation between the two variables.
WebMar 4, 2024 · Pearson’s correlation coefficient ( Pearson product-moment correlation coefficient) is the most widely used statistical measure for the degree of the relationship between linearly related variables. It is denoted by letter r. Pearson’s r is calculated by dividing the covariance of these two variables by the product of their standard deviations.
