Document Summary

The game plan today is to talk mostly about data in two dimensions. We"ll start out by talking about contingency tables before then going on to the main topic, which is linear regression and the circus that comes with it. At the beginning of class, you should: check in with me for attendance and turn in your homework, load the scatterplot data from my website under the recitation 03 data link. By load , i mean that you should download the data, save it to your working directory for r, and then load it into r and call it grade. data . The le itself is called stat101scores. csv : talk about the children question, which we didn"t discuss in last class, with a neighbor. This can be found in section 1. 2: fill in the contingency table in section 1. 3. We"ll come back to the last three points and talk about them as a class, although probably not in the order presented.
