TY - CHAP M1 - Book, Section TI - Chapter 9. Experiments When Each Subject Receives More Than One Treatment A1 - Glantz, Stanton A. Y1 - 2012 N1 - T2 - Primer of Biostatistics, 7e AB - The procedures for testing hypotheses discussed in Chapters 3, 4, and 5 apply to experiments in which the control and treatment groups contain different subjects (individuals). It is often possible to design experiments in which each experimental subject can be observed before and after one or more treatments. Such experiments are generally more sensitive because they make it possible to measure how the treatment affects each individual. When the control and treatment groups consist of different individuals, the changes due to the treatment may be masked by variability between experimental subjects. This chapter shows how to analyze experiments in which each subject is repeatedly observed under different experimental conditions.
