This book chapter is an interesting read. It illustrates the importance of considering sample size, especially, when looking at preliminary research findings.
After looking up the book from which this chapter is excerpted, I followed other recommendations from Amazon to another very useful book,
When Can You Trust the Experts: How to Tell Good Science from Bad in Education by Daniel T. Willingham, a very astute psychologist with an interest in education policy.
