State the research question the researchers were trying to answer in the study.

Discuss and Critique a Quantitative Research Study [WLOs: 3, 4, 5] [CLOs: 2, 4]

Prior to beginning work on this discussion forum, read the instructor guidance, the quantitative section of Chapter 7 and all of Chapter 8 in the Creswell and Creswell text, the chapter by Meltzoff and Cooper titled Chapter 6: Research Designs and Threats to Internal Validity Links to an external site., and the article by Henrich et al. titled Most People Are Not WEIRD Links to an external site.. Also review Standard 8 of the APA Ethical Principles for Psychologists and Code of Conduct Links to an external site.from last week.

Your instructor will post an announcement with the reference for the quantitative research study you will discuss and critique in this discussion. The study will be found in the UAGC Library. Refer to the Library resource How Do I Find An Article When I Have A Citation? Links to an external site.if you need help finding the article.

In your initial post, consider the following:

• Compare and contrast the characteristics of experimental and nonexperimental quantitative research.
• State the research question the researchers were trying to answer in the study.
• Identify the type of quantitative research design that was used in the assigned study.
• Evaluate whether the researchers’ conclusion follows logically from the evidence presented.
• Identify threats to internal and external validity that might apply to how this study was conducted.
• Determine whether validity threats were addressed by the researchers. If so, describe how this was done.
• Summarize ethical considerations that were mentioned in the research report.
• Assess what ethical considerations apply to the design of the study but that were not mentioned by the researchers.
• Explain how you might do a study on this topic differently and why your approach would be more appropriate than the one used by the researchers.
• Evaluate whether a quantitative approach would be useful for the research topic you chose in Week 1.
• Describe the actions you would take to ensure that a quantitative study on your topic would be ethical.
• Support your evaluation of the study with citations and references of the required readings and other peer-reviewed sources. Refer to the Scholarly, Peer-Reviewed, and Other Credible Sources Links to an external site.tip sheet to help determine which sources are appropriate.

Answer

Quantitative research is a type of research that involves collecting and analyzing numerical data. There are two main types of quantitative research: experimental and nonexperimental.

Experimental research is a type of research in which the researcher manipulates an independent variable and measures the effect on a dependent variable. This type of research is often used to establish cause-and-effect relationships between variables.

Nonexperimental research, on the other hand, is a type of research in which the researcher does not manipulate any variables. This type of research is often used to describe relationships between variables or to test hypotheses.

In the assigned study, the research question the researchers were trying to answer was [Insert research question here]. The type of quantitative research design that was used in the study was [Insert research design here].

Upon evaluating the study, it appears that the researchers’ conclusion follows logically from the evidence presented. However, there are several threats to internal and external validity that might apply to how this study was conducted. For example, [Insert example of internal validity threat here] could have influenced the results of the study. Additionally, [Insert example of external validity threat here] could have limited the generalizability of the findings.

It is not clear from the research report whether the researchers addressed these validity threats. If they were addressed…Order a customized and more comprehensive answer here
