MATU-203 Final Project Instructions

QUESTION

MATU-203 Final Project Instructions

Mastering the concepts in Introductory Statistics assists in building critical thinking skills, developing businesses and organizations, and solving all types of problems that require data. But an understanding of statistics extends beyond the ability to crunch numbers or use a software program.The ability to collect, organize, and analyze data is the beginning. The ability to clearly communicate your results to another person is the mark of true mastery.

The Assignment

In this assignment, you will choose a scenario with data – from one of 5 options provided at the end of these directions under Project Topics – and you will construct a paper that pulls together the statistics you have learned in order to answer a question. You will:

1. 1. Introduce the main question, and explain the data that you will use to address it
2. 2. Organize your data by providing appropriate charts, graphs and descriptive statistics 3. Analyze your data by conducting a hypothesis test
3. 4. State your conclusions and recommendations

See the section Outline Of Material To Present below for a more detailed explanation of what you will submit for each of these four sections.

The topics that you may choose from are

•    Business – Analysis of Home Sales

•    Health Sciences – The Effect of Caffeine on Heart Rate

•    Psychology – The Effect of Colored Paper on Reading Speed

•    Sociology – Level of Education and its Effect on Homelessness in Veterans • Criminal Justice – Analysis of Poverty and Crime

At the end of these directions, under Project Topics, are the full descriptions for each of these 5 topic options, including the data you must use in your analysis. Please scroll down and read through each of these 5 options in their entirety before making your selection. You must select one of these 5 topics. You may not select your own topic.

Outline of Material to Present

This assignment is broken down into four parts: Collection of Data, Organization of Data, Analysis of Data, and Conclusion/Recommendations. Each part has a subset of questions and issues you must address. Please ensure that your report includes a section for each of the 4 Parts listed below, and that each part addresses ALL of the sub-questions listed.

Again, you must select one of the 5 topics provided at the end of these instructions in the section Project Topics, and you must use the data and names provided within your chosen topic prompt.

Part 1: Collection of Data – Introduction and Primary Data Analysis (3 – 5 paragraphs):

1. 1. Describe the objective: Before you can examine the data, you must understand the problem. a. Discuss the importance of this issue or situation.
2. b. Introduce the company or organization you are preparing this report for, and explain why it is important to them.
3. c. What is the research question? In other words, what is the basic question you, as the researcher, want to address? Why should we care about it?
4. d. Was this an experimental or observational study? Explain.
5. 2. Clearly and with sufficient detail, describe the population, sample, and collection methods in this study.
6. a. What is the population you are interested in? b. What is the sample, specifically?
7. c. What is a plausible way the sample was chosen and why?
8. d. What problems or biases might have occurred from choosing that type of sampling method?
9. 3. Discuss the type of data.
10. a. Was the data quantitative or qualitative? Explain.
11. b. What is the level of measurement (nominal, ordinal, interval and ratio)? Explain. 4. Describe the variables
12. a. What are the independent and dependent variables? Give the type, units, and more specific information.
13. b. Give examples of any confounding variables, lurking variables, and/or missing variables and explain how they may be affecting your study.

Part 2: Organization of Data – Examination of Descriptive Statistics (graphs and tables, and approximately 4 paragraphs)

Now that your data is collected, you need to organize it to identify characteristics and patterns.

1. 1. Graph your data appropriately. Construct a scatter plot, bar graph, or other graph to show the nature of the data. For each graph, be sure you label the graph completely – that means give it a title, label the axes, and explain what that graph means in the context of this narrative.

2. Discuss whether the data is normally distribute For this, use a visual inspection of a Histogram and Normal Quantile Plot, as well as what you see in the data itself and what that means about the high and low ends of the data.

3. 3. Calculate and present the three Measures of Central Tendency: mean, median, and mode. Provide both the value of the statistics as well as an analysis of what they mean in terms of understanding the sample.
4. 4. Calculate and present the Measures of Variation: range and standard deviation. Provide both the value of the statistics as well as an analysis of what they mean in terms of understanding the sample.
5. 5. Calculate and present the 5-Number Summary: minimum, Q1, median, Q3, maximum. Provide both the value of the statistics as well as an analysis of what they mean in terms of understanding the sample.
6. 6. Identify any Outliers. You can do this using a visual inspection of the graph as well as the formulas from the textbook (HINT: Q1 – 1.5*IQR, and Q3 + 1.5*IQR).
7. 7. Discuss any corrections: Based on your inspection of the outliers are there any errors that should be corrected? How would you correct them? Discuss the implications of this result.

Part 3: Analysis of Data – Examination of Inferential Statistics (tables of results, and appropriate hypothesis test steps)

Assuming that all assumptions have been met, it is now time to analyze the data. Present a complete hypothesis test.

1. 1. Identify the claim.
2. 2. State the null and alternative hypotheses, in words and in symbolic form.
3. 3. Explain what type of test you will be performing (i.e. a test of two dependent means, a test for correlation, etc.) and why that test is appropriate to address the main question you are trying to answer.
4. 4. Select the significance level and determine if it is a one or two-tailed test.
5. 5. Identify the test statistic and compute the value of the test statistic and the p-value. 6. Make a decision of whether to Reject or Fail to Reject the null hypothesis.
6. 7. Restate your decision in nontechnical terms. That means, state your conclusion in a way that anyone can understand; a final conclusion that just says “reject the null hypothesis” by itself without explanation is not helpful to those who hired you. Explain in ordinary terms what it means.

Part 4:Conclusion and Recommendations(approximately 3paragraphs) Summarize and explain your results. Provide recommendations.

1. 1. 1. What can you infer from the statistics?
   2. 2. What information might lead you to a different conclusion? 3. What variables are missing?
   3. 4. What additional information would be valuable to help draw a more certain conclusion?
   4. 5. What qualitative or quantitative data would you want to collect if you were hired to do a follow up study?

Formatting Requirements

Your paper should be a Word document, with embedded charts, graphs, figures, and tables. It should be APA or MLA Format, with name and page number on each page, and should include each of the following:

1. 1. Title page: You should have a cover page. The cover page should have the specific title of your study(Note:“MATU203Paper”does not clearly define the topic you are presenting),your name,Brand man University,MATU203,term,and year.You might find it helpful to include an image of something representative of the study to provide a visual context for your report.
2. 2. Write Up/Body:The bodyshouldbe5 -8 pages with graphs, images, screen shots of data output, and text included. Please use a “page break” to separate the cover from the body and the references from the body and the appendices from the reference page.
3. 3. References: Please include all articles, books, websites, publications, or other information that helped you reach your conclusion. The references come after the main body and before the appendix. At least two references are required, not including the textbook.
4. 4. Appendices: You must have an appendix. The appendix goes at the end of your paper and might be an additional 1-2 pages. In the appendix, include your given data as well as supplemental charts and graphs outside of the ones included in your paper. Label the appendices, Appendix 1, Appendix 2, and so on.
