1 Discussion: What is this residual plot telling us about the relationship between speed and braking distance? Let’s now end by discussing how to interpret the residual plots below…

2 Discussion: 1. Can we come up with any general rules in regards to interpreting residual plots?

3 Quote of the week: “Correlation Is Not Causation”
Correlation does NOT mean that one thing causes the other. There could be other reasons the data has a good correlation

4 Example: Sunglasses vs Ice Cream
Our Ice Cream shop finds how many sunglasses were sold by a big store for each day and compares them to their ice cream sales: The correlation between Sunglasses and Ice Cream sales is _______. Does this mean that sunglasses make people want ice cream?
