Statistics
Occassionally, instead of using overheads, I make information available
on web pages (which I then project onto a screen in class).
Below are some that may be of general use.
Please let me know if you
find any errors or have suggestions for improvement.
These are interactive demos that I have written all or part of for use in
my courses. Those that require JAVA are indicated.
These are other interactive demos that I have used

Old Faithful Eruption Times. Investigate histogram bin sizes.

Normal Distribution Applets from
Seeing Statistics.
My
favorite of these can be used to find the percentage of a
normal distribution (with user specified mean and standard deviation)
that lies between any two values by dragging the edges of the shaded
portion of a normal probability curve.
 Sampling Distributions, Confidence Intervals, etc.

Correlation Coefficient and Regression Lines.

Monty Hall Problem. This problem was made famous by a serious
of articles run in the Ask Marilyn column.
Here are some demos of the problem:

This is one of several
games available from the
CUWU Statistics Program.

The
Let's
Make a Deal version done by Webster West includes an explanation.

The
MSTE Monty's Dilemma page adds an extra twist: you may keep you
original choice, switch, or flip a coin to decide.
This applet also allows you to select one of the three strategies and
run it repeatedly and tabulate the results.

the Marilyn is Wrong!
website which seeks to document any of her errors but also has interesting
information about her and her column.
There are many JAVA applets around to demonstrate various statistical
concepts and procedures. The sites below have lists or indexes of
such applets.

WebStat by Webster West looks a lot like Minitab.

Statlets
 a multifeatured JAVAbased statistics package, with free WWW access
for small datasets (10 variables x 100 cases). Produced by NWP Associates,
Inc.

Statiscope.
A one page univariate stat pakage done by Mikael Bonnier  Lund, Sweden.
Stuff for Offline Stats Packages

Fathom
is not available as a JAVA applet, but a demo version is available for
download. I have heard great things about Fathom as software for teaching
statistics.

Wolfram provides information (and a free pallette) for doing
Statistics with Mathematica
Here are links to some lists of links put together by others.
Several textbook authors and publishers
have a lot of information online that is of use even if you
aren't using their textbook. Here are some:

Survey 101:
A white paper about designing a good survey.

"Do You Believe the Polls?"  a chat with J.A. Paulos
 Places to find articles

Chance News. Chance News is an electronic newsletter that
collects articles about statistics. Often these include
interesting questions for discussion in class.
It is possible to search past issues as well as to read current issues.
Also at this location: links to
lectures with audio, video and overheads on a variety of statistics topics.

New York Times
I have occassionally made use of videos in my classes. Theses links give
either simple time outlines of the videos or (in some cases) questions I
have used related to video segments. I have included time outlines
of videos that I have previewed, even if I have never used them.
