The Sxy calculator is designed to determine the covariance between the independent (X) and dependent (Y) variables.
The formula to compute Sxy is:
Sxy = Σ(x_{i}  x̄) (y_{i}  ȳ)
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 (b_{1}) of the regression line in simple linear regression.
b_{1} =
