The new version of Statistics for the Terrified has now been released
for PC networks, and is compatible with NT, Windows 98 and 95. A more
flexible pricing system has been introduced, based on the annual number
of users.

BACKGROUND INFO
Learning statistics is a perennial problem for students and research
workers from non-mathematical backgrounds. Most simply want to be able
to apply statistics in their chosen field. By approaching it as a tool
to be used rather than an academic discipline, a higher degree of
understanding and flexibility can be achieved. Much of this can be
attained through repeated, varied and directed observation, accomplished
in this tutorial by turning the learning of statistics into a game.

Statistics for the Terrified provides a thorough grounding in
undergraduate and research statistics for the non-mathematician, and can
be used by others who wish to acquire a good working knowledge of
statistics. The program is widely used in UK colleges and universities,
and in commercial organisations.

Statistics for the Terrified incorporates a series of computerised
challenges and games, which the user plays by changing the data. This is
a radical departure in statistics teaching, where data is typically
sacred and immutable. This interactive approach involves the student
directly. By displaying simple, interactive, graphical representations,
the mechanics of Statistics become clear and a genuine intuitive
understanding is gained. In addition there are animations, challenges
and randomly generated simulations illustrating concepts such as
sampling, confidence intervals, etc.

NEW IN THIS VERSION:
Improved graphics and navigation
History and search facilities
Improved glossary
Larger display (800 x 600)
Progress log
User guide
Content summaries to print
V4.5 is 32-bit software

SINGLE-USER VERSION
A single-user version of Statistics for the Terrified, v4.0, is also
available on CD at 29.95 pounds sterling. This has all the key features
of v4.5 and is ideal for home use and non-networked use within
organisations.

AREAS COVERED INCLUDE
Simple data description: comparing the mean and median; range and
variance; the coefficient of variation; the normal curve; box and
whisker plots.

Standard error and confidence intervals: sample means and population
mean; understanding standard error through sampling; estimating the se
of the mean from the population sd; confidence intervals are based on
the se of the sample mean; a 95% CI contains the population mean 95% of
the time.

What does p<0.05 really mean?: sampling and the distribution of the
population mean; critical regions and type I errors; power and type II
errors.

How to choose a test: data layouts and pattern recognition; group
comparisons; repeated measurements, related measurements, classification
tables; appropriate tests.

Testing for differences between groups: two sample t-test; oneway
analysis of variance; twoway analysis of variance; Mann-Whitney test;
Kruskal-Wallis test.
Analysing repeated measures: before/after tests; paired t-test; Wilcoxon
signed rank test; area under a curve.

Analysing 2x2 classification tables: risk; relative risk; expected
values; the chi-square test; sample size; constraints (Fisher's exact
test).

Fitting lines to data: gradient; intercept; correlation; outliers.

Uncovering hidden influences: illustration of hidden dangers in
interpretation; analysis of covariance; twoway analysis of variance;
matching groups to avoid bias.

PRICING
Up to 25 users - 299 pounds sterling.
Next 25 users - 10 pounds sterling per user
Next 250 - 7 pounds sterling per user
After 250 - 5 pounds sterling per user

Version 3 upgrade - Holders of site licences for v3.0 should deduct 199
pounds sterling from the total fee for the initial licence for v4.5.

This licence is renewable annually. Specific renewal dates can be
arranged on request. The number of users is defined as the total number
of users that run the programme during the licence period, or where this
cannot be measured the total number of machines that run (or can run, if
this cannot be measured) the programme during the licence period.
