### Other readings

- Data Analysis for Politics and Policy by Edward Tufte. Out of print, but available for free in electronic form. I will often assign supplemental readings out of this book.
- Statistical Modeling: A Fresh Approach by Daniel Kaplan. Great book, great exercises. The first five chapters are available for free (half-way down the page under the “Read Online” heading). You will find the first one especially helpful in learning some basic R commands. You are not required to buy this book, but you may find it a useful resource. Readings will be assigned out of the first five (free) chapters.
- Using R for Introductory Statistics. A useful guide on doing basic statistics in R.
- OpenIntro: Statistics. A free online statistics textbook that I will refer to many times throughout the semester for supplemental readings.
