Class Notes 12/11

Today in class we worked more on chapter 10. The only way this chapter will make sense is to keep looking at examples and practicing. The more scatter plots you look at that are not straight, the easier this section will become. For instance if you look at a scatter plot that has an exponential curve, we want to log all the y-data in order to straighten the curve. The more examples you actually try the easier it will be for you to identify which operation you need to do to your original scatter plot.

Homework Due 12/15: Alligator Task

Class Notes 12/9

Today in class we started covering Chapter 10, re-expressing the data. In this chapter we learn that not all data is a linear model and even if it is sometimes the residual plot shows a pattern (the today's in class example) if that's the case we have to re-express the data.

Today was a little more complicated than anticipated and because of that I have decided to push back the investigative task (Alligators) until Tuesday 12/15.
