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.

If you've found value from reading my content, feel free to support me in even the smallest way you can.
