Prepare an experimental design scenario as an alternative proposal for your term project based on the experimental knowledge you have acquired. Focus on problems most commonly encountered in business.
- List the major classifications of experimental design.
- Specify the three conditions and four criteria indispensable for causality.
- Distinguish between internal and external validity and identify threats to each that endanger the results of a study.
- Explain why a true experimental design is regarded as the most accurate form of experimental research and describe the role of a control (or comparison) group in relation to the treatment.
- Support the position that it is unethical to withhold treatment from a control group in instances where the treatment provides substantial benefit.
- Classify other randomized designs that rely on random assignment to produce group equivalence, to balance treatment and control groups, or to compensate for confounding variables.
- Explain the advantages of a quasi-experiment and how it promotes increased realism and ecological validity when conditions only vary naturally (not by researcher manipulation).
- Illustrate how matching and other techniques balance treatment and control groups to reduce the effect of confounding variables.
