What is the Correlation Coefficient Calculator?

The Correlation Coefficient Calculator is a statistical tool used to measure the strength and direction of the linear relationship between two variables, X and Y. By entering paired data values for X and Y, the calculator computes the Pearson correlation coefficient (r), which ranges from -1 to 1. A positive value indicates a direct relationship (as X increases, Y increases), a negative value indicates an inverse relationship (as X increases, Y decreases), and a value near 0 suggests little or no linear relationship.

How to Use:

1. Enter X Values: Input numeric values separated by commas.
2. Enter Y Values: Input corresponding numeric values, also separated by commas. The number of X and Y values must be equal.
3. Click “Calculate”: The calculator determines the correlation coefficient (r) and displays it along with the entered values.
4. Interpret Results: Use the value of r to understand the strength and direction of the linear relationship between the two variables.
