Section 1 - INTRODUCTION
The purpose of this paper is to direct browsers/readers
to websites that typify the various sorts of resources which are currently
available via the World Wide Web to help support statistics instruction.
Due to the rapidly evolving nature of the Web, some links may no longer
be available, some may have radically modified content, and new resources
are appearing at a steady rate. We will update these links periodically
to try to provide a current snapshot of the status of WWW resources for
teaching statistics. Your assistance in pointing out dead links and suggesting
additional resources to be included is greatly appreciated. Comments can
be sent to email@example.com
Section 2- On-line Course Materials
More and more instructors are providing course materials
to their students through websites. In addition to providing convenient
access for students, these pages can be perused by instructors at other
institutions looking for hints and ideas to improving their own courses.
Note: Course below may become unavailable as semester offerings change
and sites restrict access to enrolled students only.
Lots of Courses
Section 3- On-line Texts
Several individuals and groups have undertaken ambitious
projects to develop statistics textbooks that can be accessed via the Web.
Section 4- JAVA Demonstrations
The emergence of JAVA as a platform-independent
web programming language has encouraged individuals to develop interactive
demonstration software that can be accessed via any JAVA-capable browser.
Some of our favorite individual JAVA applets (selected from the sites listed
Correlations - a neat "game" to show the relationship between correlations
and scatterplots - ten minutes should get the ideas across to almost any
student. Part of the CUWU Statistical Program at Illinois-Champaign-Urbana.
- see the effects of adding an outlier (Webster West - S. Carolina).
- check the effect of bin size on Old Faithful data (Webster West - S.
of a "Small" Effect - visualization of the impact of a difference in
group means on job candidate selection (Mark Lane - Rice).
of a Hypothesis Test - nice graphical look at power for a test of a
mean (Todd Ogden - S. Carolina).
Make a Deal version done by Webster West is quick to play and includes
The sites below contain collections of JAVA
applets or links to applets at various locations which are relevant to
Statistics Packages available as JAVA applications
over the Web:
- created by Webster West at the University of South Carolina
Statlets - a multi-featured
JAVA-based statistics package with fee-based web access and a free downloadable
version for small datasets (8 variables x 50 cases). Produced by Statpoint.

Section 5- Electronic Journals & Newsletters
Section 6 - Discussion Lists and Newsgroups
These e-lists allow instructors to share questions,
ideas and announcements related to teaching statistics, practicing statistics,
and statistical computing. Although e-mail discussion lists are part of
the wider Internet resources, the websites which archive the messages also
provide good resources for searching through past discussions.
of Apstat-l This list was set-up to support high school
teachers doing an Advanced Placement course in Statistics. Lots of
good conversation about teaching an introductory course.
of Edstat-l (and several other discussion lists) are maintained by
Information Service. This was one of the first electronic discussion
lists devoted to teaching issues.
Fuller's List of Statistical Lists A number of other e-mail discussion
lists are maintained for specific countries (e.g. Australia, Brazil,
Italy, New Zealand), statistical topics (e.g. Bayesian methods,
experimental design, time series analysis), subject areas (e.g.
biometry, geography, econometrics), and software packages (e.g.
Minitab, SPSS, SAS).
Section 7- Data, Data, and More Data
Need an example of a regression which is drastically
altered by an influential outlier? Want to find some data to illustrate
descriptive statistics which will appeal to students interested in environmental
issues? Looking for a multivariate dataset to serve as the basis for next
week's midterm exam? Have a student who loves horse racing and wants to
use data from past runnings of the Kentucky Derby for her project? The
Web is the place to find loads of data sources, often in downloadable formats.
Pages of Links to Datasites
Government & Official Agencies Data
There's tons of data produced by various govenment
departments, although it often takes a bit of digging to find it.
Data About the Web
Want to measure some feature of Web pages? You'll
need a way to randomly sample pages...
Or to check how a sample of colleges and universities
present themselves via the web...
Generating simulated data
Project - online simulation of data from several scenarios with an
empahsis on experimental design. Produced by a group at the Univ.
of Colarado at Boulder, based on software developed at the Univ. of Michigan.
- sample from the population of this online town, with demographics generated
from real Canadian census data -brought to you by Carl Schwarz at Simon
What data do STUDENTS choose from the web?
Section 8- Miscellaneous Links
Sites with good general links related to teaching
Need some questions for that next quiz or exam,

Other sites to start browsing
Data - an excellent collection of links and resources for teaching
an introductory level course. Part on-line text, part on-line course materials,
and all well-presented by Rex Boggs at Glenmore HS in Rockhampton, Australia.
Instruction Internet Palette (SIIP) - a project directed by John Behrens
at Arizona State.

section related to teaching statistics, put together by Clay Helberg at
Guide to the
Web for Statisticians - lots of general statistical links with good
sections on teaching and data, maintained by Gordon Smythe at University
Section 9- Conclusion
The development of the World Wide Web has produced
unprecedented means for instructors to easily share their ideas on ways
to improve the teaching of statistics. The links presented here represent
some of the types of resources that are currently avaialble, but are by
no means an exhaustive list of the many excellent websites that help support
statistics instruction. Although the volume of on-line material may
seem daunting, and the process of searching for worthwhile information
can be frustrating, the rewards, both for instructors and our students,
can be quite substantial. If current trends continue, universal access
to the Web should become easier, faster, and more common, on-line applications
should become even more sophisticated, and useful resources should continue
to appear at a steady rate.
