Assignment 2

[faykisteroff]

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

• evaluating the structure of the data, visualizing variables, and creating a linear regression model.

What did you learn from the changes you have made?

• the process of examining the dataset and creating a linear regression model.

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

• there are other ways to evaluate the relationship between a variable and predictor variables in the dataset (ex., K nearest neighbours (KNN) and KNN linear regression.

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

• I had some initial trouble with finding the top 5 rows in the horsepower column, as initially I used mpg_data['horsepower'].head(5), but this did not sort the data in the way I needed. I searched through my previous class notes and online for a way to include a sort feature as well.

How were these changes tested?

• all cells were executed as I was entering the code to make sure that it was working properly before continuing on to the next question.
