WebWe describe correlations with a unit-free measure called the correlation coefficient which ranges from -1 to +1 and is denoted by r. Statistical significance is indicated with a p-value. Therefore, correlations are typically written with two key numbers: r = and p = . The closer r is to zero, the weaker the linear relationship. WebNov 21, 2024 · In a linear regression the coefficient of correlation, r, varies between -1 and +1. If the p-value value is under the significance level, we have to reject the null hypothesis, the null-hypothesis being here that there is no linear relationship between 2 variables.
