Pearson S R Correlation Test. Whenever any statistical test is conducted between the two variables then it is always a good idea for the person doing analysis to calculate the value of the correlation coefficient for knowing that how strong the relationship between the two variables is. The stronger the association between the two variables the closer your answer will incline towards 1 or 1.
The first step in studying the relationship between two continuous variables is to draw a scatter plot of the variables to check for linearity. Pearson s correlation coefficient r is a measure of the strength of the association between the two variables. To perform the pearson correlation test use the cor test function.

These are the two variables that you want to correlate in the pearson correlation. To perform the pearson correlation test use the cor test function. The correlation coefficient should not be calculated if the relationship is not linear. The cor test function requires two inputs.
