Webb3 maj 2024 · An assumption of the Pearson correlation coefficient is that the joint distribution of the variables is normal. However, it has been shown that the correlation coefficient is quite robust with regard to this assumption, meaning that Pearson’s correlation coefficient may still be validly estimated in skewed distributions [ 3 ]. Webb28 maj 2024 · Based on the result of the test, we conclude that there is a negative correlation between the weight and the number of miles per gallon ( r = −0.87 r = − 0.87, p p -value < 0.001). If you need to do it for many pairs of variables, I recommend using the the correlation function from the easystats {correlation} package.
