Formula for Sxy in linear regression

The formula for the sum of the products of the differences between the x-values and the y-values in linear regression (often denoted as Sxy) is:

Sxy = Σ((x – x̄)(y – ȳ))

where:

  • Sxy = Sum of the products of the differences
  • Σ = sum of a series or summation.
  • y and x = individual data points
  • x̄ and ȳ = Averages of the x-values and y-values

How to calculator Sxy

To calculate Sxy, you can use the following steps:

  1. Calculate the mean (average) of the x values.
  2. Calculate the mean(average) of the y values.
  3. Subtract the mean of the x values from each x value, (x – x̄)
  4. Subtract the mean of the y values from each y value,(y – ȳ)
  5. Multiply the x values and y values
  6. Sum the products that you just calculated.

This sum will give you the value of Sxy.

How to use the Sxy calculator?

Enter all date x values in the X input field (eg:- 1,2,3,4,5,6,4) then enter all data sets of Y variable in the y input field (eg:- 2,2,3,3,5,9,4,5,6) then click calculate button then you will get sxx, syy and sxy values
