This chapter utilized the central epidemiological strategy — comparison of populations — to discuss bias. Bias, in an epidemiological context, arises when errors affect comparison groups unequally. Since this is often the case, perhaps always the case, bias is a central issue in epidemiology. Classification of error and bias and a practical application of the research chronology schema are discussed.

Keywords:   classification of error, public health, epidemiological studies, errors, bias
