Pearson Correlation Coefficient Calculator. The Pearson correlation coefficient is used to measure the strength of a linear association between two variables, where the value r = 1 means a perfect positive correlation and the value r = -1 means a perfect negataive correlation. So, for example, you could use this test to find out whether people's height and weight are correlated …

19.11.2015 · Take the number you calculated first [Σ (X-Mx) (Y-My)] and divide it by the number you just got [ (N-1)SxSy]. Interpret your result. r is the symbol used to denote the Pearson Correlation Coefficient). Anything above .7 is a very strong …

Example of Pearson Correlation Coefficient Formula

Dec 03, 2019 · The Pearson Correlation Coefficient (which used to be called the Pearson Product-Moment Correlation Coefficient) was established by Karl Pearson in the early 1900s. It tells us how strongly things are related to each other, and what direction the relationship is in! The formula is: r = Σ(X-Mx)(Y-My) / (N-1)SxSy

The Pearson correlation coefficient is denoted by the letter “r”. The formula for Pearson correlation coefficient r is given by: \[\large r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^{2}-(\sum x)^{2}][n\sum y^{2}-(\sum y)^{2}]}}\] Where, r = Pearson correlation coefficient x = Values in the first set of data y = Values in the second set of data
