This **correlation coefficient calculator** can help you test the correlation coefficient between two statistical variables x and y. There is in depth information about the formula used below the form.

## How does this correlation coefficient calculator work?

This is a statistics calculator that can help in determining the coefficient correlation between two variables within a given data set, we use to call x and y.

The values for the 2 variables x,y, should be separated ONLY by commas, and they should stay one pair per line as exemplified below:

x1,y1

x2,y3

x3,y3

x4,y4

x5,y5

The algorithm behind this *correlation coefficient calculator* uses the Pearson’s formula as presented here:

Where:

The Karl Pearson’s correlation coefficient measures the linear dependence between two variables *x* and y*. *It can have a value between +1 and −1 inclusive, where 1 is total positive correlation, 0 means no correlation while −1 is total negative correlation.
