Find r correlation coefficient
WebAug 11, 2024 · To find the Pearson correlation coefficient, r, you must complete the formula. This formula is divided into a numerator and denominator. The numerator consists of the following equation: nΣxy – ΣxΣy. The denominator consists of the following equation: √ [nΣx 2 – (Σx) 2] [nΣy 2 – (Σy) 2] WebFind out the Pearson correlation coefficient from the above data. Solution: First, we will calculate the following values. The calculation of the Pearson coefficient is as follows, r = (5*1935-266*37)/ ( (5*14298- (266)^2)* (5*283- (37)^2))^0.5 = -0.9088 Therefore the Pearson correlation coefficient between the two stocks is -0.9088.
