Correlation Coefficient Calculator
Find the Pearson correlation coefficient between two datasets.
Assumptions used in this calculation
- Linear relationships only: Pearson's r only detects linear association; two variables with a strong non-linear (e.g. curved) relationship can still produce an r close to 0.
About this calculator
The correlation coefficient calculator finds Pearson's r, measuring the strength and direction of the linear relationship between two sets of x/y data.
Worked example
5 data points
Result: r = 0.7746 (strong positive)
