Document Summary

Five basic research strategies: experimental, non-experimental, quasi-experimental, correlational, and descriptive. A researcher can often devise a research strategy (a method of collecting data) that is similar to an experiment but fails to satisfy at least one of the requirements of a true experiment. Such studies are generally called non-experimental or quasi-experimental research studies. Although these studies resemble experiments, they always contain a confounding variable or other threat to internal validity that is an integral part of the design and simply cannot be removed. The existence of a confounding variable means that these studies cannot establish unambiguous cause-and-effect relationships and, therefore, are not true experiments. The distinction between the non-experimental research strategy and the quasi- experimental research strategy is the degree to which the research strategy limits confounding and controls threats to internal validity. If a research design makes little or no attempt to minimize threats, it is classified as non- experimental.
