Web3 jan. 2024 · The Pearson correlation coefficient (also known as the “product-moment correlation coefficient”) is a measure of the linear association between two variables X and Y. 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 Web8 feb. 2024 · For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak. When we are studying things that are more easily countable, we expect higher correlations.
