WebbProperties. The Pearson product-moment correlation coefficient (population parameter ρ, sample statistic r) is a measure of strength and direction of the linear association between two variables. In other words it assesses to what extent the two variables covary. Although Pearson (1895) developed the mathematical formula that is still most ... Webb2 apr. 2024 · Method 1: Using the p-value Method 2: Using a table of critical values In this chapter of this textbook, we will always use a significance level of 5%, α = 0.05 NOTE Using the p-value method, you could choose any appropriate significance level you want; you are not limited to using α = 0.05.
