A correlation coefficient measures the extent to which two variables tend to change together the coefficient describes both the strength and the direction of the relationship minitab offers two different correlation analyses: pearson product moment correlation the pearson correlation evaluates the. Quaestiones geographicae 30(2) • 2011 comparison of values of pearson's and spearman's correlation coefficients on the same sets of data. Why use correlation we can use the correlation coefficient, such as the pearson product moment correlation coefficient, to test if there is a linear relationship between the variables. In statistics, the pearson correlation coefficient (pcc, pronounced / ˈ p ɪər s ən /), also referred to as pearson's r, the pearson product-moment correlation coefficient (ppmcc) or the bivariate correlation, is a measure of the linear correlation between two variables x and y.
The sampling distribution of pearson's r is normal only if the population correlation (ρ) equals zero it is skewed if ρ is not equal to 0 (click here for illustration) ) therefore, different formulas are used to test the null hypothesis that ρ = 0 and other null hypo.
