## Handouts

The handouts are marked with helpful icons. A full explanation of the icons is available, and most browsers will also show a “tool tip” if you just hover your mouse over the icon.

### Chapter 1: Data Collection

#### 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: Graphical Summaries

#### Optional extras

• The Joy of Stats video: Hans Rosling shows lots of great ways to present data (accessed 2012-03-25). Don’t miss the segment “200 Countries, 200 Years, 4 Minutes”, also available separately (accessed 2012-03-25).
