Pearson's r meaning

WebOct 12, 2024 · Back to r. As stated above, Pearson’s correlation coefficient (r) for continuous data ranges from -1 to +1. This means that if r = -1, the data lies on a perfectly straight line with a negative slope. Also, if r = +1, the data lies on a perfectly straight line with a positive slope. If r = 0, this means there is no linear correlation. WebFeb 8, 2024 · Effect size is a quantitative measure of the magnitude of the experimental effect. The larger the effect size the stronger the relationship between two variables. You can look at the effect size when comparing any two groups to see how substantially different they are.
