Sxy Calculator

Sxy is a measure that quantifies the degree to which two variables (X and Y) vary together. It helps in determining the direction and strength of the relationship between these variables. Mathematically, Sxy is expressed as:

Sxy=∑(Xi​−Xˉ)(Yi​−Yˉ)

• Xi ​ and 𝑌𝑖  represent individual values of the independent and dependent variables, respectively.
• Xˉ and 𝑌 are the means of the X and Y values, respectively.
• ∑ denotes the summation over all observations.

Sxy is a critical metric in linear regression analysis, as it helps to determine the direction and strength of the relationship between two variables. Understanding and accurately calculating Sxy is essential for developing meaningful linear regression models. By following the steps outlined in this guide, you can confidently compute Sxy and apply it to your data analysis projects.
