$\begingroup$ This is the approach I usually take, as it has the added benefit of sidestepping painstaking justification of one test vs. another, particularly when testing correlation among many variables. Rather than examining each variable to see whether the assumptions of Pearson or Spearman correlation are met, just run both on everything.

Kendall rank correlation: Kendall rank correlation is a non-parametric test that measures the strength of dependence between two variables. If we consider two samples, a and b, where each sample size is n , we know that the total number of pairings with a b is n ( n -1)/2 . The Pearson correlation coefficient value of 0.877 confirms what was apparent from the graph, i.e.

Pearson correlation test

The Pearson correlation method is the most common method to use for numerical variables; it assigns a value between − 1 and 1, where 0 is no correlation, 1 is total positive correlation, and − 1 is total negative correlation. This is interpreted as follows: a correlation value of 0.7 between two variables would indicate that a significant and positive relationship exists between the two.

In simple words, Pearson’s correlation coefficient calculates the effect of change in one variable when the other Pearson’s Correlation. Pearson correlation coefficient quantifies the linear relationship between two variables. It can be any value that lies between -1 to 1. The positive and negative value indicates the same behavior discussed earlier in this tutorial.
