8210 WK 9 ASSGNMENT

Assignment: Multiple Regression in Practice

For this Assignment, you will continue your practice as a critical consumer of research. You will critically evaluate a scholarly article related to multiple regression.

To prepare for this Assignment:

· Use the Course Guide and Assignment Help found in this week’s Learning Resources and search for a quantitative article that includes multiple regression testing. Also, you can use as guide the Research Design Alignment Table located in this week’s Learning Resources.

For this Assignment:

Write a 3- to 5-paragraphs critique of the article (2 to 3 pages). In your critique, include responses to the following:

· Why did the authors use multiple regression?

· Do you think it’s the most appropriate choice? Why or why not?

· Did the authors display the data?

· Do the results stand alone? Why or why not?

· Did the authors report effect size? If yes, is this meaningful?

Use proper APA format, citations, and referencing.

Week Nine: Multiple Regressions

Posted on: Friday, July 22, 2022 9:31:03 AM EDT

As social scientists, we frequently have questions that require the use of multiple predictor variables. Moreover, we often want to include control variables (i.e., workforce experience, knowledge, education, etc.) in our model. Multiple regression allows the researcher to build on bivariate regression by including all of the important predictor and control variables in the same model. This, in turn, assists in reducing error and provides a better explanation of the complex social world.

Example: a local school system is trying to mitigate poor attendance. The researchers may look at several, possible interventions. In the end, a study may find a combination of interventions will work better than any single one. This finding is a typical product of multiple regression. In addition, because combinations of data may need to combined, a researcher can infer. The word is a power word in social sciences as it empowers a researcher to synthesize and speculate based upon responsible use of data.

In the end, having concluded your analysis of a regression, what has been learned? In two sentences or less what can you share with others?
