Humphrey, Watts S. A Discipline for Software Engineering. Reading, MA: Addison-Wesley, 1995. Appendix A of Humphrey's book contains a short, readable summary of statistical techniques that are useful for software estimation.

Stutzke, Richard D. Estimating Software-Intensive Systems, Upper Saddle River, NJ: Addison-Wesley, 2005. Chapter 5 of Stutzke's book goes into more detail on some of the statistics presented in this chapter. Chapter 20 describes how to create a WBS.

Gonick, Larry and Woollcott Smith. The Cartoon Guide to Statistics. New York, NY: Harper Collins, 1993. Despite the silly title, this is a respectable (and fun) introduction to statistical techniques. Many readers will find the extensive illustrations help them learn the statistical concepts. Some readers might find that the focus on pictures rather than text makes the concepts harder to understand.

Larsen, Richard J. and Morris L. Marx. An Introduction to Mathematical Statistics and Its Applications, Third Edition. Upper Saddle River, NJ: Prentice Hall, 2001. This book is a fairly readable, traditional introduction to mathematical statistics; at least it's readable when you consider the subject matter. It's an unavoidable fact that if you want to use statistical techniques, sooner or later you'll have to do some math!
