ORDER NOW FOR COMPREHENSIVE, PLAGIARISM-FREE PAPERS
Part I
The first part of the assignment you must choose an article based upon a research proposal . Select a research article of interest to you, preferably related to your Research Proposal, and use the Research Evaluation Worksheet to analyze the article. You can use this information to help form the literature review section of your research proposal.
**Please note that the research is due in a couple of weeks, however; choose an article based upon the intended proposal**Below you will see an example of how the proposal should look, again this is not the assignment due, but I just want to make sure the article chosen is acceptable. Wk4 Assignment Discussion Paper
You want to create a potential title in the form of a question, for example:
“What is the effect of [the name of a program, intervention or initiative] on [psychological outcome or behavior] for [target population]?
For example: “What Is the Effect of Social Support on the Severity of Postpartum Depression Among Adolescent Mothers”
Part II
The second part of the assignment, you must use the attached chapters 8-10 to answer the worksheet. Wk4 Assignment Discussion Paper

Research Proposal PSYCH/610 Version 2
1 University of Phoenix Material
Research Proposal
Develop an original research study proposal and describe it in detail in a 10-12 page (APA style) paper. Include at least 10 scholarly references in your proposal. Use the following outline as a guide when writing your paper. Be sure to include detailed information on all of the topics listed below and use headings to organize your thoughts. Wk4 Assignment Discussion Paper
1. Statement of the problem: Introduce the reader to the problem to be studied. Provide sufficient background information such that the reader has a grasp of the situation and its importance.
2. Review of the literature: Provide the reader with a review of most relevant literature, beginning with general information, and narrowing the focus to the specific issues under consideration in the study.
3. Purpose of the study: Identify why the study that you are proposing is needed.
4. Hypotheses or research questions: List them as simple statements. Make sure they are measurable.
5. Definition of terms: Operationally define terms the average reader may not know, or that have a specific meaning in your study.
6. Assumptions: Identify issues you assume to be true in order for your study to be valid.
7. Research methods and procedures
a. Population: Describe the population sample to be studied
b. Procedure: Discuss how the study will be carried out.
c. Instruments: Describe the specific measurements (instruments) to be used to test each hypothesis (research question).
d. Data Analysis: Describe the procedures you intend to use to analyze the data produced from your instruments, and how that would answer the hypotheses (research questions).
e. Discussion: Since you are only proposing (not conducting) a research study, you will not have results; however, you can discuss potential outcomes. Review your hypothesis and discuss how this study will address it. For example, if the results allow you to reject the null hypothesis, what are the implications? What would happen if you fail to reject the null hypothesis? Discuss the implications of your proposed study, the limitations of your study, and future research ideas and directions.
f. Since you are only proposing (not conducting) a research study, you will not have results; however, you can discuss potential outcomes. Review your hypothesis and discuss how this study will address it. For example, if the results allow you to reject the null hypothesis, what are the implications? What would happen if you fail to reject the null hypothesis? Discuss the implications of your proposed study, the limitations of your study, and future research ideas and directions.
8. Implications: Provide a brief summary of your proposal and a powerful statement as to how your study would advance the field.
9. References: Include at least 10 scholarly sources in your Reference section. Be sure to use APA style throughout your paper.

:
1. What is a confounding variable and why do researchers try to eliminate confounding variables? Provide two examples of confounding variables.
2. What are the advantages and disadvantages of posttest only design and pretest-posttest design?
3. What is meant by sensitivity of a dependent variable?
4. What are the differences between an independent groups design and a repeated measures design?
5. How does an experimenter’s expectations and participant expectations affect outcomes?
6. Provide an example of a factorial design. What are the key features of a factorial design? What are the advantages of a factorial design?
7. Describe at least four different dependent variables (examples not definitions).
8. What are some ways researchers can manipulate independent variables?
9. What is the difference between main effects and interactions?
10. How do moderator variables impact results? Provide an example.
11. A researcher is interested in studying the effects of story endings on preference ratings. He randomly assigns participants into two groups: predictable ending or surprise ending. He instructs them to read the story and provide preference ratings. The experimenter’s variation of story endings is a __________ (straightforward or staged) manipulation.
12. A researcher was interested in investigating the vocabulary skills of 6th graders in a program for gifted students. She gave a group of participants a test of vocabulary that was aimed at the 7th-grade level. She quickly discovered that there was limited variability in the scores because nearly all the students answered 90% or more of the questions correctly. This outcome is called a _______ effect.
