# SPSS Excel Covariance, Correlation, Least Squares Method

This SPSS Excel tutorial explains how to calculate Covariance, Correlation and Least Squares Method in Excel and SPSS. Covariance and Correlation When we plot a scattered graph to see the relationship between two interval variables, we can see how straight a line is formed (whether the relationship is strong) and whether the relationship is positive or negative (upward or download). However, when we want to look deeper to see the strength of the relationship, we need to calculate covari...
