The pearson correlation coefficient r is

WebbThe Pearson correlation coefficient is a value that ranges from -1 to 1. The major cut-offs are: -1 – a perfectly negative association between the two variables 0 – no association between the two variables 1 – a perfectly positive association between the two variables WebbPearson’s correlation coefficient is the test statistics that measures the statistical relationship, or association, between two continuous variables. It is known as the best …

Pearson’s Correlation Coefficient SpringerLink

WebbThe solution is to (1) take the standard deviations of each variable, (2) multiply them together, and (3) divide the covariance by this product – the resulting value is called the Pearson correlation coefficient. When referring to the population correlation coefficient, the symbol ρ (pronounced “rho”) is used.

WebbThe Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable.
