Introduction to Regression
- Last workshop, we learned about classification.
- In this workshop, we will learn about regression.
- Regression is all about predicting something from something else.
Scenario 1: Cube Towers
- We want to build a tower
- We have 1” inch cubes to use

Let’s Predict!
NOTE: This needs to be a series of slides when moved to slides.qmd…
- Let’s predict the height of our tower, given the number of cubes we use.

How tall will our tower be if we use 100 cubes? How do you know?
Scenario 2: Cheap Uncle Bob
- We want to build a much taller tower, but we ran out of 1” cubes.
- Uncle Bob has a plan. He volunteers to make us more cubes for cheaper than we can buy them.
- Bob makes us a lot of cubes:
Oh no! Uncle Bob’s cubes are of all of slightly different heights!
How will our new cubes from Uncle Bob affect our tower height predictions?
