Histogram Applet (Chapter 4) Uses Old Faithful data to show how number of bins used in a histogram can give different impressions of the distribution.

Least Squares Demo (Chapter 8)

Data-Fitting Demo Using Least Squares and Least Absolute Value (Chapter 9) Useful for showing the effect of influential points and points with high leverage. Shows the line fit by the Least Absolute Value method as well as the least squares line. Choose "least square line" (at top), then use "Add points" (at the bottom) to put in some points; the least squares line for those points will be shown. Click "move point" at the bottom to be able to move a point and see how the least squares line changes. (Choosing the other top buttons will allow you to show the Least Absolute Value line, or both lines, and see how they behave differently in response to moving a point.)

Wording Questions (Chapter 12) More examples and references about wording questions for surveys. Might be useful for students who want to do a survey asking a question.

Bad Copy (Optional supplement for Chapters 13 and/or 18 and/or 20 -- 20 might be best; or for your own background) A recent article in Nature discussing how studies may give different results when replicated, and some related problems

(Chapter 17, p. 412) Several links showing the binomial distribution and normal approximation:

Sampling Distribution/Central Limit Simulations (Chapter 18))

Agresti
Sampling Distributions demo

Several choices of population
distribution (including "custom"). Shows sampling distributions for a
couple of statistics. See instructions on website. Choosing binary and
looking at the sampling distribution of count of 1's shows the binomial
distribution as a sampling distribution.

Rice
Virtual Lab in Statistics Sampling Distribution Demo

This allows you to create a
distribution for Y and simulate the sampling distribution for the mean
of Y with various sample sizes. It also shows summary statistics for
the sampling distribution. To see cases where the convergence of the
sampling distribution to normal is very slow, try the following:

1. A distribution with a full height
spike at the left, a half height spike at the right, and nothing in
between, with n = 25.

2. A distribution with three equally spaced spikes, descending in height, with nothing in between.

2. A distribution with three equally spaced spikes, descending in height, with nothing in between.

Simulations Shows distributions of sample means for samples of
sizes 2, 4, 16, and 32 for a zoo of distributions, some ordinary and
some exotic.
