WISE (from Claremont Graduate University)
-- a wide range of resources that are freely available on the Internet. Contains
a sequence of interactive tutorials on key statistical concepts (sampling
distributions, the central limit theorem, hypothesis testing, and statistical
power). The tutorials use dynamic applets that allow the user to explore
relationships on their own. Guided exercises are designed to help the learner
to take full advantage of the applets to gain a deeper understanding of the
concepts and logic that underlie much of inferential statistics.

graduate students working on their dissertations. Their web site also provides

StatGames
-- 20 games—or challenges—that will help you test and
refine your statistical thinking. Not a substitute for a statistics course,
but may give you an enjoyable opportunity to develop your statistical reasoning.
-
Choosing
Neighbors -- implements Thomas Schelling's mathematical model of residential
segregation. "REDs" and "GREENs" live in the same neighborhood. You get to
chose how many of each live there, and you get to choose the minimum number
of like-color neighbors each wants. (Many people like living in integrated
neighborhoods, but most don't want to be the only one of their color there.)
The program lets people move around the neighborhood until their wishes are
met. See what happens when non-racists just don't want to be alone.
-
Statistical
Chart Tutor -- helps students learn to read statistical tables:
distributions, scatterplots, regressions, and cross-tabulations (the last
with and without control variables).
-
StatQuiz
-- contains hundreds of multiple-choice questions that will help you test
and develop your statistical reasoning. The questions are organized into
10 categories (corresponding to the chapters in this statistics textbook:
Introduction to Statistical Reasoning, WCB/McGraw-Hill, 1998 ). After you
answer each question, you will see a brief explanation of why your selected
answer is correct or incorrect.
-

Interactive Statistics Pages), and links to other reference material
on the Internet.

An On-line, Interactive, Computer
Adaptive Testing Mini-Tutorial -- When an examinee is administered a
test via computer, the computer can update the estimate of the examinee's
ability after each item and then that ability estimate can be used in the
selection of subsequent items. With the right item bank and a high examinee
ability variance, CAT can be much more efficient than a traditional
paper-and-pencil test. This excellent tutorial lets you learn the logic of
CAT and see the calculations that go on behind the scenes. You can play with
an actual CAT (items and correct answers provided); try different scenarios
and see what happens;pretend you are a high ability, average or low ability
examinee; intentionally miss easy items; and get items right that should
be very hard for you.
-
Spatial
Autocorrelation game -- given an initial random assortment of integers
which fill a , rearrange them to alter the spatial autocorrelation to maximize
it, minimize it, or even to drive it to zero.
-
Interactive JavaScript
quizes on using SPSS and interpretation of results. Also contains other
SPSS-related resources.
-
An excellent
demonstration of the use of the Chi Square test for analyzing contingency
tables. Using one of several pre-loaded sample datasets, you specify
the variables to be cross-tabbed; the program then generates a detailed analysis,
from which you can interactively explore the effects of merging rows and/or
columns in the table.
