Abstract:

The paper deals with statistical studies of human populations designed to investigate either analytical relationships among a number of variables or subgroups in the population, or some more specific cause-and-effect relationship e.g., seat belts and injuries in auto accidents. Such studies are called non-experimental in the sense that the investigator cannot apply the causal agent to randomized groups of people. The three topics discussed are i preliminary aspects of planning, ii some simple types of study plan and analysis, and iii techniques for increasing precision and guarding against bias. Author
