WebWhat is Pearson product-moment correlation PDF? Pearson's Product Moment Correlation Coefficient - Pearson's r. Pearson's r is a measure of the linear relationship between two interval or ratio . variables , and can have a value between -1 and 1. It is the same measure as the point-biserial. 1.0 INTRODUCTION. WebJan 6, 2016 · Pearson's r measures the linear relationship between two variables, say X and Y. A correlation of 1 indicates the data points perfectly lie on a line for which Y increases as X increases. A value of -1 also implies the data points lie on a line; however, Y decreases as X increases. The formula for r is clutch online shop
