possible without sacrificing technical
correctness

Conclusion and Summary
Histograms and Bar Charts
To help students distinguish the
histogram from the simple bar chart,
for the data here is the example
from page 39 of the Histograms Chapter
(Chapter 3) which also mentions the
advantage of the histogram for larger
data sets.
Histogram, Box Plot, and CDF
To compare and contrast these three
basic exploratory charts, here is the
example from page 83 of Chapter 4 on
Landmark Summaries.
Probability Trees
Probability is less
mysterious to students
when there is a visual
framework, as shown here
in the example from page
144 of Chapter 6.

Hypothesis Testing
Hypothesis testing is more
intuitive when the
confidence interval
method is used (as shown
here from pages 253-254
of Chapter 10). The
traditional t-statistic is also
presented in detail.
Bivariate Data Examples
Relationships and regression are powerful
business concepts. Here are a couple of the
examples from Chapter 11 on Bivariate Data
(pages 295 and 308).
Magazine Ads and Multiple Regression
The cost of advertising can be explained, in part,
by magazine characteristics such as audience
size and income level in this example that is used
to illustrate the power of multiple regression in
business, from Chapter 12.
Excel Guide
The Excel Guide goes step-by-step through,
chapter by chapter, to show students how Excel
can be used to obtain statistical results. Here is
the scatterplot example from page 82 of the
Excel Guide.
