# Simple Linear Regression

## Introductions

*Icebreaker:* What game are you analyzing for Project 4?

## Groupwork

- Think about an answer yourself
- Discuss your answer with your partner(s)
- Write down your joint answer

In simple linear regression, the y-intercept (b) represents the:

- predicted value of Y
- change in Y per unit change in X
- predicted value of Y when X=0
- variation around the line

A simple linear regression model for predicting a player's points (Y) is 6 X + 10, where X is the player's level.

- How many more points can a player expect to get when they level up?
- How many points can a level 10 player expect to get?

## Hand-in

Have ONE person from each group submit the group's answers:
