ASSIGNMENT 1.

PSY 520 Short Paper Two Guidelines and Rubric

Describe a potential mediator and moderator that could apply to each research finding below.

Before you describe a potential mediator and moderator in each research situation, you should clearly explain the concept of mediators and moderators. Defining mediators and moderators is a separate grading criterion on the grading rubric.

In each research scenario here, define the mediator and moderator. Supply evidence in your narrative to support your definitions of the mediator and moderator for each research situation.

1. High satisfaction with ones direct supervisor leads to lower levels of employee turnover. In other words, employees who are highly satisfied with their direct supervisor are less likely to leave an organization than employees who are dissatisfied with their direct supervisor (DeConinck, 2009).
2. High levels of parental reading are associated with faster cognitive development in young children. In other words, children whose parents read to them more show faster cognitive development than children whose parents read to them less often (National Scientific Council on the Developing Child, 2007).
3. The experience of being socially excluded leads to increases in aggressive behavior. Research has found that when people are excluded by others, they are more likely to behave aggressively, even to people who did not initially exclude them (Twenge et al., 2001).
4. Defendants who wear glasses are less likely to be convicted by juries as being guilty of committing violent crimes (Brown et al., 2008).

Specifically, be sure to address the following critical elements:

• Provide an explanation of mediators.
• Provide an explanation of moderators.
• Include an accurate application of mediators to research situations. Identify potential mediators and correctly explain why they are applicable.
• Include an accurate application of moderators to research situations. Identify potential moderators and correctly explain why they are applicable.

What to Submit

Submit a 2- to 3-page document with double spacing, 12-point font, and one-inch margins, using APA format for any sources cited.

ASSIGNMENT 2

Find a peer-reviewed article that discusses a mediator or a moderator. You are encouraged to find an article related to your final project topic, but you may also use one of the articles listed here:

Describe the nature of the relationship the mediator or moderator has to the independent and dependent variable.

Does the general way that the author describes the mediator or moderator seem to fit with the process outlined by Baron and Kenny (1986) in ? Try not to get too bogged down with the statistics of the mediator and moderator tests. Focus on the general principles.

When responding to your classmates, provide a scholarly perspective on whether the mediator or moderator is being interpreted and explained correctly.

ASSIGNMENT 3

PSY 520 Journal One Guidelines and Rubric

The Data Analysis Plan journal assignment will prepare you to analyze your data in Module Six when you complete the Milestone Four assignment. This journal is a chance for feedback on appropriate and inappropriate statistical tests. This data analysis plan is new. Do not submit the data analysis plan from PSY 510.

The journal assignment is designed to develop a data analysis plan that is workable next week. It is challenging to enter Module Six without a solid analysis plan. Now is the time to think about how you will analyze your data. Provide substantial information for your instructor to give you feedback.

In the Milestone Four assignment you complete later, you will report the data that you analyzed with your data analysis plan. The Descriptive Statistics and Findings are the results of the analysis with APA descriptive statistics tables, p values, tests of significance, etc. Check the Milestone Four rubric for more information.

In this journal assignment, briefly describe the level of data collected in your survey. Then describe how you plan to analyze the data you collect. Specifically, which statistical test(s) will you use, and why? What variables might you examine with a specific test?

Which tests will you not use, and why? Remember:

• PSY 510 introduced you to:
  • Measures of central tendency
  • Measures of variability
  • Correlation
  • Comparing means (t-tests)
• PSY 520 covers:
  • Multiple regression (in Module Four)
  • Factorial ANOVA (in Module Six)
  • Repeated measures (in Module Seven)
  • Chi-square (in Module Eight)

Remember that you are not simply planning to analyze data. You will actively analyze your data later in this course! This journal assignment is a chance to have your instructor provide feedback on your data analysis plan to ensure that you are on the right track. The journal positions you for successful analysis in Milestone Four. It is challenging to analyze and report your findings, so it is helpful to start carefully thinking about it now.

Although you will lack enough survey responses to use many statistical tests (such as t-tests, ANOVA, regression, etc.), you may use them for educational purposes in this assignment.

Prompt

1. Provide a description of data collected in the survey. What level of data did your survey collect (e.g., nominal, ordinal, interval, ratio)? A survey might have nominal data in the demographic items and interval/ratio with a Likert scale. The level of data allows you to decide the appropriate statistical test to use. Showing the levels of data allows your instructor to supply valuable feedback about statistical tests.
2. Name the survey items used to collect descriptive data and explain the descriptive statistics tests you will conduct on your data. Descriptive statistics often describe participants demographics items. Items in the demographic information often are nominal or categorical data. Measures of central tendencies are the correct statistical tests to use and report.
3. Describe the statistical tests you plan to use and why you chose them.
4. Discuss statistical tests that would be inappropriate to use and what makes them inappropriate.
5. Define the variables you plan to use with each statistical test you conduct. For example, you might use an independent t-test to compare dog owner and non-dog owner scores on an anxiety scale. You would use an independent t-test for two groups (dog owner/non-dog owner), each measured once.

What to Submit

Submit your 2- to 3-page document with double spacing, 12-point font, and one-inch margins, with any sources referenced cited in APA format.
