Problems in Designing an Experimental Research Study Problems in Designing an Experimental Research StudyPrior to beginning work on this discussion, please read the required articles by Skidmore (2008) and Henrich, Heine, & Norenzayan (2010). Carefully review the PSY635 Week Two Discussion Scenario. Apply the scientific method to the information included within the scenario and develop a null and a research hypothesis based on it. Using the hypotheses you have developed, compare the characteristics of the different experimental research designs discussed in the Skidmore (2008) article and choose the one that is most appropriate to adequately test your hypotheses. Identify potential internal threats to validity and explain how you might mitigate these threats. Apply ethical principles to the proposed research and describe the implications of this type of research in terms of the population(s) and cultural consideration(s) represented in the sample(s) within the scenario.Guided Response: Review several of your colleagues posts and respond to at least two of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies earlier in the week to promote more meaningful interactive discourse in this discussion. Answer Preview The null and research hypothesis based on the scenario. The null hypothesis based on the scenario given is that changing
the instruction plan and design for the discussion prompts will not increase students participation in the discussion forums. On the other hand, the research hypothesis will be changing the instruction plan and design for the discussion prompts will increase students participation in discussion prompts. Comparison of the characteristics of the different experimental research designs discussed in the Skidmore (2008) article with my hypotheses and selecting the one that is most appropriate to adequately test your hypotheses. Skidmore (2008) article uses three experimental designs to find answers to the hypothesis. The designs have several differences despite having a few similarities. They are the Pretest-Posttest Control-Group Design, the Posttest-Only Control Group Approach, and the Solomon Four-Group Design. The first two approaches uses a random assignment and intervention design, which is implemented on the experimental group only, and also uses the post-intervention measurement. However, the two designs are different in that the second design does not use the pre-intervention measurement, hence controls the possible confounding effects. On the other hand, the Solomon-Four Group technique controls the likely confounding pretest effects. However, it allows the researchers to compare the findings of the experimental group
