**To prepare**

- Review the datasets provided.
- Construct a research question with social change implications based on one of those datasets.
- Be sure to focus on the assumptions of this test and ask yourself, “Does it make sense to interpret the mean of this dependent variable?”
- Remember that you will need categorical predictor variables.

By Day 7

**The Assignment**

Use SPSS to answer the research question you constructed. Then, compose a 1- to 2-paragraph analysis in APA format in which you answer the following questions:

- What is the null hypothesis for your question?
- What research design(s) would align with this question?
- What dependent variable was used and how is it measured?
- What independent variable is used and how is it measured?
- If you found significance, what is the strength of the effect?
- What is the answer to your research question?
- What are the possible implications of social change?

Be sure to include your data output with your analysis

Section B

For this Assignment, you will critically evaluate a scholarly article related to factorial ANOVA.

**To prepare**

- Review the Article Critique Assignment Guide in the Walden Library, listed in the Week 2 Learning Resources.
- Search the Walden Library for a quantitative article that applies factorial analysis of variance. Note that sometimes these are referred to as “two-way ANOVAs.”

By Day 7

**The Assignment**

Write a 2- to 3-page critique of the research you found in the Walden Library that includes responses to the following prompts:

- Why did the authors select factorial ANOVA in the research?
- Do you think this test was the most appropriate choice? Why or why not?
- Did the authors display the results in a figure or table?
- Does the results table stand alone? In other words, are you able to interpret the study from it? Why or why not?
