Reading Assignment: Garfinkel - 4, 7; Smith Databanks; Sweeney 2001; Sweeney 2002

1. (30 points) Write a short summary of each chapter or article in the reading assignment (2-5 sentences each). After each summary (in a separate paragraph) provide a "highlight" for that chapter. This can be something new you learned that you found particularly interesting, a point you would like to discuss further in class, a question the chapter did not fully answer, something you found confusing, a point you disagree with, or anything else you found noteworthy.

2. (20 points) Select a piece of personal information and document at least five ways that information might be inferred through public or semi-public sources. For each source, comment on the quality of the information that can be obtained. (This is explained further in problem 2 on page 25 of the Sweeney 2001 article.)

3. (25 points) The table below contains information from the course roster for our class. Suppose some researchers were interested in finding out whether there was any correlation between grades in this class and student college, department, or class.
