WebMar 25, 2024 · One way to quantify the relationship between two variables is to use the Pearson correlation coefficient, which is a measure of the linear association between two variables. It has a value between -1 and 1 where: -1 indicates a perfectly negative linear correlation between two variables 0 indicates no linear correlation between two variables WebWhat do the values of the correlation coefficient mean? The correlation coefficient r is a unit-free value between -1 and 1. 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.; Positive r values indicate a positive correlation, …
