# M358K Instructor Materials

Feel free to use any of these as is, or use parts and/or ideas for your own handouts. Most of these are pdf files, but I can provide .doc versions for most of them at your request.

Note: Since I am revising these materials as the occasion arises, I suggest reloading when you come back to this page, in order to get revised versions.

## External Links

These are links to websites mentioned in the Notes for Instructors (linked above). You may want to use some of them for in-class demonstrations of concepts. (I recommend trying them out before class to decide how best to use them.)

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.
Mary Parker's 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.

Log-Normal Distribution (possible supplement to Chapter 18 for interested students)

Agresti Confidence Intervals for a Proportion demo (Chapter 19)

Agresti "Significance Tests for a Proportion" web demo (Chapters 20 and 21)
See description and instructions on web site, as well as comments in Notes for Part V.

Possible supplemental reading for Chapter 20:
Confidence Intervals for the Mean web demos (Chapter 23)
Severe Diet Doesn't Prolong Life, at Least in Monkeys NY Times science reporter Gina Kolata discusses recent research on the effect of diet restriction.  A nice supplement to the ActivStats activity “Compute a Confidence Interval for the Restricting Diet Data” for Chapter 24.
