Pearson's correlation coefficient analysis
WebNov 22, 2014 · The Pearson correlation coefficient measures the linear relationship between two datasets. Strictly speaking, Pearson's correlation requires that each dataset be normally distributed. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. 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.
