Sxy Calculator for Linear Regression

The Sxy calculator is designed to determine the covariance between the independent (X) and dependent (Y) variables.

How to Use the Sxy Calculator?

1. First, input the list of independent (X) and dependent (Y) values with a comma or space delimiter. Example: 5,10,15 or 5 10 15.
2. Click the 'Calculate' button to obtain the Sxy result.

How to Calculate Sxy?

The formula to compute Sxy is:

Where,
x_i = Each value of the independent variable,
x̄ = Mean of X dataset,
y_i = Each value of the dependent variable,
ȳ = Mean of Y dataset.

The Sxy is used to compute the slope (b₁) of the regression line in simple linear regression.
