Throughout the Course
Chapter 1: Statistics!

has lots of true random number generators, including numbers, coin
flips, and dice rolls.

Chapter 2: Graphing Your Data
- The Joy of Stats video: Hans Rosling shows lots of great ways to present data (accessed 2014-12-28). Don’t miss the segment “200 Countries, 200 Years, 4 Minutes”, also available separately (accessed 2014-12-28).
- just for fun: self-referential graphs

- MATH200A Program part 1 can be used to make histograms.
- ticalc.org has five programs to make pie charts. Though I haven't evaluated them in depth, PIEGRAPH.ZIP looks most interesting based on the screen shots.
- STEMLEAF.ZIP (1 KB) is a TI-83/84 program that makes stemplots
Chapter 3: Numbers about Numbers
Chapter 4: Linked Variables
- How do we know there’s one best line? How does
the calculator know what it is? See

how do we know that smoking causes cancer? Steve Simon tells you.
- Under Chapter 12 are several more inferences you can make about correlation and regression.

- What is a normal distribution? by Steve Simon gives an overview with diagrams. Near the bottom of the page there’s a downloadable spreadsheet that draws normal distributions.

by Gerald Dallal — pictures show how sample means are distributed and why that distribution is different from the shape of the population.
Chapter 9: Estimating Population Parameters
