How to Calculate and Interpret a Correlation (Pearson's r)
This video covers how to calculate the correlation coefficient (Pearson’s r) by hand and how to interpret the results. Here we use the 'definitional formula' for calculating the correlation, as it is the easier of the two methods. It also makes more sense intuitively than the computational approach to calculating the correlation coefficient ...

Pearson Correlation Calculator
The Pearson correlation measures the strength and direction of the linear relation between two random variables, or bivariate data. Linearity means that one variable changes by the same amount whenever the other variable changes by 1 unit, no matter whether it changes e.g., from 1 1 1 to 2 2 2, or from 11 11 11 to 12 12 12.. A simple real-life example is the relationship between parent's ...

How do I calculate the p-value for correlation? The p-value for Pearson correlation is calculated using: 1) The correlation coefficient (r), 2) Sample size (n), and 3) A t-test with n-2 degrees of freedom. The formula is t = r × √((n-2)/(1-r²)). This calculator automatically computes the p-value for you using these steps.
