How to Calculate a Pearson Correlation Coefficient by Hand

WebPearson called his equation the product moment correlation coefficient. We typically now refer to it as the Pearson's r. The calculation is based on the concept of the Z scores; specifically, taking the mean of the Z score products from the X and Y variables. The formula for Pearson's r is: WebJan 14, 2024 · Pearson's r ranges from -1 −1 to +1 +1; The closer it is to \pm 1 ±1, the stronger the relationship between the variables; If r equals -1 −1 or +1 +1, then the linear fit is perfect: all data points lie on one line; and If r equal 0 0, it means that no linear relationship is present in the data. hdfc bank sahakar nagar branch
