Portfolio Project: US Medical Insurance - Regression Analysis and Z-score Normalization

I will attempt to link to my GitHub Repo for this project here. I’m new to this.

This was a fun project. I enjoyed every step.

Big Decisions made:

  • I opted to use linear regression to relate BMI to Insurance Costs (similar to the Reggie’s Linear Regression Project)
  • I decided to normalize BMI and Insurance Costs to Z-scores before analyzing because neither variable would natively include a zero, or anything close.
  • I decided to test the variable globally, and also by gender
  • I wanted to display my results graphically. I don’t have that skill yet, so I leaned on ChatGPT to help me with Seaborn and Matplotlib to get this step done.

Do you agree with my conclusions? I added a conclusions and future consideration section to my Jupyter Notebook, and I’m open to your critiques.
