This is an excellent, pithy little book, which cuts to the heart of the issues that are central to statistics and epidemiology.
It begins with the basics of quantitative description of disease in groups. The authors present the process of epidemiologic inference, including discussions of disease intensity, risk, and the like.
Next, the student encounters the basics of statistical inference. Probability, sampling, and statistical significance are discussed within the framework of biologic variability.
The authors then apply these tools to the assessment of exposure and disease associations, as would take place in epidemiologic or clinical research. A comprehensive and versatile measure of association the product moment correlation, is discussed. Although not widely used in epidemiology, that particular correlation measure provides an excellent didactic model for the understanding of association. It makes sense to present it as it is in this text. Once the product moment correlation is understood, the student
