Research Report(DUE 11/14/16

Write a research report based on a hypothetical research study. Conducting research and writing a report is common practice for many students and practitioners in any of the behavioral sciences fields.

A research report, which is based on scientific method, is typically composed of the different sections listed below:

Introduction: The introduction states a specific hypothesis and how that hypothesis was derived by connecting it to previous research.
Methods: The methods section describes the details of how the hypothesis was tested and clarifies why the study was conducted in that particular way.
Results: The results section is where the raw uninterpreted data is presented.
Discussion: The discussion section is where an argument is presented on whether or not the data supports the hypothesis, the possible implications and limitations of the study, as well as possible future directions for this type of research.

Together, these sections should tell the reader what was done, how it was done, and what was learned through the research. You will create a research report based on a hypothetical problem, sample, results, and literature review. Organize your data by creating meaningful sections within your report. Make sure that you:

Apply key concepts of inferential hypothesis tests.
Interpret the research findings of the study.
Examine the assumptions and limitations of inferential tests.
Develop a practical application of the research principles covered in this course.

Focus of the Research Report

To begin, create a hypothetical research study (you do not have to carry out the study; you will just have to describe it) that is based on the three pieces of information listed below. Once you have your hypothetical study created, write a three- to four-page research report (excluding title and reference pages) that outlines the study. You are encouraged to be creative with your research study, but be sure to follow the format outlined below and adhere to APA formatting as outlined in the Ashford Writing Center.

Your hypothetical research study should be based on the following information:

Recent research has indicated that eating chocolate can improve memory. Jones and Wilson (2011) found that eating chocolate two hours before taking math tests improved scores significantly. Wong, Hideki, Anderson, and Skaarsgard (2009) found that women are better than men on memory tests after eating chocolate.
There were 50 men and 50 women who were randomly selected from a larger population.
A t-test was conducted to compare men and women’s performance on an assessment after eating chocolate. The results showed an independentt-test value of t .05(99) = 3.43; p < .05

Your research study must contain the following:

Title Page
Title of your report
Your name
The course
Instructor
Date
Introduction
Introduce the research topic, explain why it is important, and present the purpose of the paper and the research question and hypothesis.
Discuss how this study is related to other research on the topic.
Elaborate on the information from the references you were given. State how they relate to your hypothesis.
Your introduction must:

Consist of a paragraph explaining what you are studying and why. Use previously cited research to explain your expectations and discuss how those expectations led to your hypothesis.
State a clear and testable hypothesis and whether it is one-tailed or two-tailed. Make sure it is understandable to someone who has not read the rest of your paper yet. State the null hypothesis.
Include a justification of the direction of your hypothesis. In other words, explain why you chose the direction of your hypothesis if it is one-tailed (e.g., previous research suggests that people with big feet are more likely to score higher on math tests; therefore the hypothesis is one-tailed) or if it is two-tailed (e.g., previous research is not clear on which group will perform better; therefore, the hypothesis is two-tailed).
Describe why this study is important.

Method

Design: State the experimental design of your study, the independent and dependent

variables, and what the task was (e.g., what you had the participants do).
Participants: Identify and describe your sample, how the participants were selected

to be in the study, and why you chose them. Provide details for how each individual was

assigned to each group.
Procedure: Describe the precise procedure you used to conduct this research (i.e., exactly

what you did). It should be clear enough that anyone could replicate your study. This is the

subsection where you tell the reader how you collected the data.
Data Analysis: Describe the statistical procedure used in the study to analyze the data.

Results: In this section, you will describe the statistical results:

State the statistical tests that were used.
Justify the choice of test.
State the observed value and significance level and whether the test was one or two-tailed.
State your conclusion in terms of the hypothesis.
Did you accept or reject the null hypothesis?

Discussion: Discuss your results as they relate to your hypothesis.

Did you accept the hypothesis or reject it?
Compare your results to the previous studies mentioned in the introduction. Are your results similar or different? Discuss why.
Tell the readers what your findings mean. Why did you get the results you did?

Identify limitations to your study.
Suggest ways your study could be improved.
Suggest ideas for future research, not just a continuation of your study, but research that is similar to this study. Perhaps one of the variables could be changed or a different sample could be investigated.
Finish with a concluding paragraph that is a statement of your findings and the key points of the discussion.

Conclusion: Write a paragraph detailing your experience with writing a research report. Discuss how easy/difficult it was to write a false report that reads like real results, and how this experience might affect you review research in the future. Do you think this experience will provide you with a useful skill in your potential career?

References: You will create a minimum of three fictitious references in the following format based on the information you have created in the preceding sections of the report:
Author, A., & Author, B. (Publication year). Title of the article. Journal Name, volume number(issue number), page numbers.
Example: Jones, A., & Williams, B. (2013). Why monkeys are good pets. Journal of Silly Science, 23(4), pp. 221-222.

Part I: Essay Questions

There are three essay questions in this section. You must answer all three questions. The length of each essay should be one to two double-spaced pages (excluding title and reference pages). Use 12-point font and format your paper with regular 1-inch margins. Do not include the essay prompt in your document. It will not count toward the length requirement for your essays.

Essay 1

A group of researchers conducted an experiment to determine which vaccine is more effective for preventing getting the flu. They tested two different types of vaccines: a shot and a nasal spray. To test the effectiveness, 1000 participants were randomly selected with 500 people getting the shot and 500 the nasal spray. Of the 500 people were treated with the shot, 80 developed the flu and 420 did not. Of the people who were treated with the nasal spray, 120 people developed the flu and 380 did not. The level of significance was set at .05. The proportion of people who were treated with the shot who developed the flu = .16, and the proportion of the people who were treated with the nasal spray was .24. The calculated p value = .0008.

For this essay, describe the statistical approaches (e.g., identify the hypotheses and research methods) used in this excerpt from a research study. Interpret the statistical results and examine the limitations of the statistical methods. Finally, evaluate the research study as a whole and apply what you have learned about hypothesis testing and inferential statistics by discussing how you might conduct a follow-up study.

Your essay must address the following points:

Describe the research question for this experiment.
What were the null and alternative hypotheses?
Were the results of this test statistically significant?
If so, why were they significant?
Would the researchers reject or fail to reject the null hypothesis?
Do the results provide sufficient evidence to support the alternative hypothesis?
Was the sample appropriate for this study? Explain your answer.
What are some possible limitations to this study?
Discuss how you would conduct a follow up study to this one. Explain your answer.
