### Chapter 1: Statistics!

#### Optional extras

• Excel and your calculator generate pseudo-random numbers, but Random.org has lots of true random number generators, including numbers, coin flips, and dice rolls.
• Read about the Literary Digest polling fiasco for the 1936 presidential election at Classic Polling Surprises (accessed 2012-03-25) and Introduction to Polling (accessed 2012-03-25).

The original Literary Digest article can be found at Landon in a Landslide: The Poll that Changed Polling (accessed 2012-03-25).

• If observational studies can’t show that A causes B, how do we know that smoking causes lung cancer? See Causation by Steve Simon.
• Alternating Treatments by Steve Simon gives lots of examples why you need to randomize your samples.
• What’s wrong with surveys where respondents select themselves? See Web Polls by Steve Simon.

### Chapter 2: Graphing Your Data

#### Optional extras
