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
