Abstract
Much of the last chapter focused on the principles, properties, and sources of individual measurements on individual subjects. As emphasized in Chapter 1, however, epidemiology is primarily concerned with groups rather than individuals. Consequently, methods are needed for summarizing or describing measurements in groups. For continuous variables, such summary measures include the mean, median, standard deviation, and other descriptors of the central tendency and spread of individual values within the group. These concepts and terms will be developed in Chapter 11.
