Lord, Harold G.
This paper presents the causal comparative method, or ex post facto research design, as an alternative to classical experimental methods for establishing causal relationships between events and circumstances. A literature survey, conducted in an effort to define and describe the method is discussed. Following this is a presentation of the relationship between the correlation method and the causal comparative method. Both the strengths and weaknesses of the ex post facto research designs are detailed. (WDR)
