By the time a text reaches a fifth edition, most of the changes from
the previous one are relatively minor: modifications based on more recent
research, newer references, perhaps some updated figures, and, if the author
is ambitious, a new chapter or two. In my experience, it is highly unusual
for a book to change its underlying structure, especially one that has been
successful through multiple editions. Having reviewed the fourth edition of Studying a Study and Testing a Test for this journal, I
was somewhat apprehensive about the new one: would I be looking over material
that I had already read? Surprisingly, the answer was no—the fifth edition
represents a radical departure from the structure of the fourth.
