In this video, you'll learn how to properly handle categorical independent variables when performing multiple linear regression analysis in Excel. Categorical data—like regions, product types, or job titles—can’t be used directly in regression without being transformed.
📚 What You’ll Learn:
- Why categorical variables need to be converted
- How to create dummy variables in Excel
- Running multiple linear regression with both numeric and categorical predictors
- Interpreting the output and avoiding common pitfalls like multicollinearity
