Next, we can use the following formulas to calculate the test statistic and the corresponding p-value: The test statistic turns out to be 4.27124 and the corresponding p-value is 0.001634. Since this p-value is less than .05, we have sufficient evidence to say that the correlation between the ... WebPearson’s correlation coefficient is the test statistics that measures the statistical relationship, or association, between two continuous variables. It is known as the best method of measuring the association between variables of interest because it is based on the method of covariance.
