locate one article from the professional psychological literature that utilizes a nonexperimental quantitative approach. The research could utilize a correlation (including regression models), ex post facto, causal comparative, survey, observational, or any other nonexperimental design covered in this unit. If you select an observational study, be sure it is quantitative, not qualitative.

For the nonexperimental study you selected, complete the following:

List the persistent link for the article in your response.

Describe the nonexperimental design used in the article.

Explain why the design exemplifies a nonexperimental approach

Describe the constructs and variables under investigation.

Describe the instrument or instruments used in the research.

Evaluate the scientific merit of the research.

Did a nonexperimental design allow the researchers to answer the research question or questions?

How might you have designed this study differently?

QUESTION NUMBER 2

Using the quasi-experimental articles you chose for the earlier, compose a discussion that addresses validity and reliability.

THIS IS THE ARTICLE :
Taylor-Covill, G. H., & Eves, F. F. (2016). Carrying a biological ‘backpack’: Quasi-experimental effects of weight status and body fat change on perceived steepness. Journal Of Experimental Psychology

Complete the following:

List the persistent link for the article in your response.

Identify the research questions, the approach (experimental, quasi-experimental, or nonexperimental), and the design used to answer the research questions.

Discuss your understanding of internal validity, and evaluate the degree of internal validity in the research study.

Discuss your understanding of external validity, and evaluate the degree of external validity in the research study.

Identify the instruments and the constructs that they measured. If more than one instrument was used, choose one to answer the rest of this point:

Evaluate the construct validity and reliability of the instrument. You may need to look for information that is not contained within the article to have the kind of information you need to evaluate the construct validity and reliability.
