# Sxy Calculator (for Regression)

-

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.

x values:

y values:

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.

Hey 👋

I'm currently pursuing a Ph.D. in Maths. Prior to this, I completed my master's in Maths & bachelors in Statistics.

I created this website for explaining maths and statistics concepts in the simplest possible manner.
