## 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.
