WebJan 3, 2024 · The scatterplot below shows the value of these two variables: The Pearson correlation coefficient for these two variables is r = 0.836. The test statistic T = .836 * √(12-2) / (1-.8362) = 4.804. According to our t distribution calculator, a t score of 4.804 with 10 degrees of freedom has a p-value of .0007. WebPearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name. ...

Pearson correlation coefficient - Wikipedia

In statistics, the Pearson correlation coefficient ― also known as Pearson's r, the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation, or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data.
