What is the Correlation Calculator (Pearson)?

The Correlation Calculator (Pearson) measures the strength and direction of the linear relationship between two datasets, X and Y. It uses the Pearson correlation formula to calculate a value between -1 and +1, where the result shows whether the variables move together, move oppositely, or have no relationship at all. By entering your values, the calculator quickly analyzes the data and provides the final correlation coefficient, helping students, researchers, and analysts understand data connection, trend behaviors, and comparison strength with clarity and accuracy.

How to Use:

1. Enter X Values: Type all X numbers separated by commas.
2. Enter Y Values: Enter the corresponding Y numbers the same way.
3. Click “Calculate”: The calculator processes both datasets instantly.
4. View Result: The output shows the Pearson correlation coefficient (r).
5. Interpret: Use the value to understand if the relationship is strong, weak, positive, or negative.
