For Tues, Nov 27

Here's what you should try to get done in OLI before next Tues:

Module 2: Screens 48 - 61 (up through checkpoint 2)

Unit 1, Mod 2: Examining Relationships Case Q-Q: Linear Relationships Causation Wrap-Up (Relationships) - StatTutor Exercise (Body_Image.xls) & Checkpoint 2

Linear relationships (calculate correlation) Linear relationships (calculate & plot regression line) StatTutor: College and high school GPAs (Question 1) Male and female body image (Question 2) Seat location and academic performance (Question 3)

In class on Tuesday, we will begin with a discussion of statistics in the big wide world. Bring to class any uses of statistics which you come across in your daily life, so we can discuss how the statistic(s) is being used.

Next we will discuss some of the concepts related to scatterplots, correlations, linear regression, and causation.

We'll also take a look at the scatterplot of m&m weight and count of m&m's, and consider whether calculating a correlation and a linear regression equation makes sense.
