UofT-DSI | LCR - Assignment 2

[alanmj950]

What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

I implemented Assignment 2 requirements, including data inspection, visualization, model fitting, and model evaluation using the Auto MPG dataset.

What did you learn from the changes you have made?

I learned how to inspect datasets (rows, columns, variable types), interpret scatter plots with regression lines, and fit/evaluate linear regression models using RMSPE.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

I considered using RMSE for model evaluation, but followed the instructions to use RMSPE instead.

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

A challenge was distinguishing between RMSE and RMSPE. I initially implemented RMSE, but after reviewing the assignment, I updated my code to correctly calculate RMSPE.

How were these changes tested?

I tested the code by running it in Jupyter Notebook, checking dataset summaries, confirming regression plots were generated, and verifying RMSPE calculations produced expected numerical outputs without errors.
