Document Summary

Overview of research designs: descriptive non-experimental, observational method, case study method, survey method, predictive non-experimental, correlational method, quasi-experimental method, explanatory experimental, experimental method. True experiments: post-test-only design, pretest-post-test design, random assignment to conditions, experimental control of all other variables, given the above, any difference on the dependent variable should be due to the effect of the independent variable. What if the heaviest smokers in the experimental condition leave the program: pre-test enables us to assess the effects of mortality, disadvantages of pre-tests, time consuming, can sensitize participants to the research questions which might influence their responses. If detection of the pre-test poses a problem, can conduct solomon four-group design. This disguises the pre-test by employing a combination of both post-test only and the pre-test post-test design: solomon four group design. If there is no impact of the pre-test, the post-test scores will be the same in the two control groups and in the two experimental groups.
