Buetow (University of Auckland) explains the primary health study designs, the need for literature reviews, purposive sampling strategies, and methods of presenting qualitative research findings. Later chapters suggest how to minimize survey errors, estimate sample sizes for randomized trials, publish a journal paper, and write effective prose. Unlike conventional texts, most of the material is arranged into tables that summarize key points, cite examples, and compare advantages with disadvantages.
