SOLUTION MANUAL INTRODUCTION
1 2 3 4
The end-of-the-chapter exercises have been designed to achieve several ends: (1) to illustrate the
5
use of techniques demonstrated in the text, thereby more effectively giving the students an
6
understanding of what they've read; (2) to extend the application of the techniques beyond what
7
was explicitly presented in the text, and (3) to probe further the theoretical principles upon which
8
the techniques are based. With over 50 years of teaching experience between us, we have come to
9
appreciate more those texts which do more than focus almost exclusively on repetitious drill in
10
their exercises, and we have sought to provide the kind and selection of exercises we most
11
appreciate when we do the teaching.
12
The difficulty of the exercises varies from fairly simple (but not trivial) to fairly
13
challenging. Many exercises require nothing more than a hand calculator, and some, not even that.
14
The more calculation-intensive exercises can be done with Excel, and, for tutorial purposes, we
15
suggest that is what the student does. The quickest way to do many exercises is with a statistical
16
software package, and some of that is encouraged. We remind the reader of the shortcoming of
17
"blindly" plugging into SPSS® or JMP®; the point of doing the exercises is to help master the
18
material, not to get the answers.
19
We have found the writing of the text and the solution manual to be a very demanding and
20
very rewarding undertaking. We hope you find reading and studying our book to be less demanding
21
and even more rewarding. If you care to share your comments, we would be receptive to having
22
them.
