Where to Go from Here
This book is written in such a way that you can start anywhere and still be
able to understand what’s going on. So you can take a peek at the table of
contents or the index, look up the information that interests you, and flip to
the page listed. However if you have a specific topic in mind and are eager
to dive into it, here are some directions:
✓ To work on finding and interpreting graphs, charts, means or medians,
and the like, head to Part II.
✓ To find info on the normal, Z-, t-, or binomial distributions or the Central
Limit Theorem, see Part III.
✓ To focus on confidence intervals and hypothesis tests of all shapes and
sizes, flip to Part IV.
✓ To delve into surveys, experiments, regression, and two-way tables, see
Part V.
Or if you aren’t sure where you want to start, you may just go with Chapter 1
for the big picture and then plow your way through the rest of the book.
Happy reading!
