Unit  6 discussion 2 of 2DISCUSSION RESPONSE ( 350 - 500 Words ) Again using your research questions (DOMESTIC VIOLENCE) and select one of the within-subjects designs (not a between-subjects design, as done for DQ1) from this week’s reading (either the single factor two- level design or the single factor multilevel design). Discuss the advantages and disadvantages of a within-subjects design, and describe ways to minimize some of the problems inherent with this approach to experimental research. Do you feel that this would be a good method to use for your hypothetical research study? Why or why not? Finally, how could you adapt this to a single-subject design, and why might you want to do so?

7 discussion 1 of 2DISCUSSION RESPONSE ( 350 - 500 Words ) In this unit, you learned about the different quasi-experimental designs that researchers use. Illustrate how you could use the interrupted time series design to answer a real-world research question through the use of archival data. How could you revise this into an experimental time series design? Finally, illustrate how you could use the nonequivalent control group design to answer a research question (DOMESTIC VIOLENCE) that interests you. Why is this approach considered quasi-experimental? a detailed description of how you would use this method in your study, and include a brief discussion of how you would handle the problem of error- variance. If a between-subjects design would not be adaptable to your study, explain why it would not. Could the study be altered to make it work?

Unit  8 discussion 1 of 2DISCUSSION RESPONSE ( 350 - 500 Words )Think of a research topic in developmental psychology that deals with aging or changes over time. Briefly describe the different developmental designs, and select one that you would use to explore this topic. Provide a rationale as to why you would use the approach that you selected and why you believe this method is preferable to the other two in this case. Describe some of the pragmatic issues that researchers face when using the developmental designs and how these issues can threaten the validity of your results. Finally, take some time to discuss the problem of generational cohorts and whether or not you feel this would be an issue in your hypothetical study.(DOMESTIC VIOLENCE)
