Assignment 2

[PSulf]

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

Submitted completed assignment_2.ipynb with all code, plots, and written answers for the Linear Correlation & Regression module. Just focusing on what's asked, no extra files or edits outside this assignment. Hopefully)

What did you learn from the changes you have made?

I reinforced how to use multivariable linear regression, interpret coefficients, and calculate model accuracy (R², RMSPE). Also got better at debugging merge and push issues in Git.

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

Thought of using .join() and alternate plotting libraries at one point, but decided to stick closely to the lesson materials to match expectations.

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

Yes — had major Git issues. The branch was misaligned, other assignment files got dragged in, and earlier PRs failed. Solved it by force-pushing only assignment_2.ipynb from a clean commit and verifying branch isolation.

How were these changes tested?

Ran all cells in Jupyter — plots render correctly, no errors, and outputs match expectations. Confirmed push was successful with --force-with-lease and verified clean diff on GitHub before opening this PR.
