Introduction:
This class will cover basic statistics including regression, how do statistical analysis, and how to find flaws and problems with statistical analyses.
In the
process of learning about data analysis you will also learn about demography
and stratification in the
Books (available at Stanford Bookstore):
* Freedman, David, Robert Pisani, and Roger Purves. 2007. Statistics. Fourth Edition. W.W. Norton. $105, ISBN: 0393929728 (recommended). If you know a little about statistics already, or if you have taken one statistics class like Stats 60, you don’t need to buy the Freedman, and you can ignore the Freedman reading assignments.
* Tufte, Edward. 2001. The Visual Display of Quantitative Information. Graphics Press. $28, 0961392142 (required).
Other readings will be linked from the class website.
Software Required (order online)
* Intercooled (IC) Stata, Version 12. You may purchase either a 1 year license for $98,or a perpetual license for $179. I recommend the perpetual license so that you can use this software in the future. The software comes with a small introduction to Stata book. Don’t bother buying Stata’s massive printed reference book collection. I will teach you the Stata commands that you need to know, and the Stata online help is very good.

Computer Use Policy:
* Computer use by students in class is strictly limited to following along with the data analysis examples being presented by the professor.
