    For a potential researcher, choosing the correct research design is essential in the battle to control variables. Because without controlling for variables, a researcher is not able to make inferences about cause/effect relationships. Correlation does not imply causation is the all-important rule that any psychology undergraduate would be able to tell you. However, some research designs can be used in the absence of some variable control measures and still implying correlational relationships.…

    The Posttest Only Control Group designs solves the reactive or interaction effect of testing by removing the use of a pretest, while the Soloman Four Group Design addresses the same issue by using experimental and control groups with and without pretests, the interaction of testing and the treatment are controlled. Additionally, this threat effects all Quasi-Experimental Designs since they lack a control group, the threat can be eliminated by using design features that include a control group. The second threat is the interaction effects of selection biases and the experimental variable, where using only posttest measures may be suggested as selection biases. Separate-Sample Pretest-Posttest designs account for this threat, by creating random assignment procedures and applying treatment before to some groups and after to others. The third threat to external validity is reactive effects of experimental arrangements, which are typically due to a subject having knowledge that they are participating in a study. This threat can affect the Equivalent Time Samples Design since it has limitation…

    Similarities between the two designs are the use of participants or subjects who agree to submit to some form of treatment or review, data is gathered from the participants and measured to see if the treatment or testing was the cause of any changes in results. Differences between the two forms of research is that in a Quasi- Experimental study participant are not necessarily chosen at random as would be in an Experimental study. The control group and the treatment group in a Quasi –Experimental study may not undergo the exact same parameters of treatment. When this occurs, different types of hypotheses may develop, questioning the validity of the findings. For instance, if a researcher wanted to study the effects of a certain cancer drug and was able to randomly select a control group, a treatment group and isolate and control the independent variable, an Experimental study would be ideal. On the other hand if a research wanted to conduct a study on the effects of proper nutrition and cancer, a quasi-Experimental study might be the better route to follow due to the lack…
