The Sxy calculator allows us to find the value of the Sxy variance on the basis of the given values of the dependent (Y) and independent variables. Simply enter the x and y values in the calculator below in order to find the value of Sxy.
Sxy = -291.00000
The Sxy variance can be found by taking the sum of the product of deviations of the x and y values from their means. It can be calculated using the formula,
Sxy = Σ (Xi – X̄)(Yi - Ȳ)
It can alternatively be calculated using the formula,
Sxy = (Σ XiYi ) – nX̄Ȳ
The Sxy value is useful to calculate the value of the regression coefficient in linear regression. It is also used when calculating the correlation coefficient.
