WebThe correlation coefficient r is a unit-free value between -1 and 1. Statistical significance is indicated with a p-value. Therefore, correlations are typically written with two key numbers: r = and p = . The closer r is to zero, the weaker the linear relationship.

WebWhere, N = the number of pairs of scores Σxy = the sum of the products of paired scores Σx = the sum of x scores Σy = the sum of y scores Σx2 = the sum of squared x scores Σy2 = the sum of squared y scores Some steps are needed to be followed: Step 1: Make a Pearson correlation coefficient table.Make a data chart using the two variables and name them as … WebThe direction, form, and strength of the relationship remain the same. Since r measures direction and strength of a linear relationship, the value of r remains the same. 2. The correlation measures only the strength of a linear relationship between two variables. It ignores any other type of relationship, no matter how strong it is. b&b pacengo
