3-3 Final Project Part II Milestone Two: Describe the Data | |

Instructions | |

With the data uploaded into StatCrunch (see the Module One non-graded StatCrunch activity for more information) and the health question you will explore identified, it is time to complete the following tasks:
· Describe the data set using summary statistics. · Identify any limitations you think the data has. · Identify the variables you will use in your study. To complete this assignment, review the Milestone Two Guidelines and IHP 525 Milestone Two Guidelines and Rubric Overview: In the Final Project Part II: Statistics Report, you have the opportunity to demonstrate your skill at selecting and calculating appropriate biostatistical measures. In Milestone Two, you will select and calculate summary statistics to describe the data set. Prompt: One way to describe data is to describe the shape, location, and spread of the data. In Milestone Two, you will select summary statistics to calculate for your data. You will also describe the source of the data and the sampling technique you think might have been used. You also need to consider limitations of the data set and the impact such limitations might have on the findings you will share later in the project. Refer to the Statistical Report Description for a description of the data set provided and uploaded in Module One. Specifically, include the following critical elements: A. Assess the collected data. Use this section to layout the source, parameters, and any limitations of your data. Specifically, you should: 1. Describe the key features of your data set. Be sure to assess how these features affect your analysis. 2. Analyze the limitations of the data set you were provided and how those limitations might affect your findings. Justify your response. Also complete the Milestone Two Table to show the summary statistics you selected and the calculations.

## IHP 525 Statistical Report Description

This document provides you with a description of the data that you will need to complete Final Project Part II Milestone Two.

*Description of the Data:*

NAME: Worcester Heart Attack Study WHAS100 Data (whas100.dat)

SIZE: 100 Observations, 9 variables

SOURCE:

Worcester Heart Attack Study data from Dr. Robert J. Goldberg of the Department of Cardiology at the University of Massachusetts Medical School.

REFERENCE:

DESCRIPTIVE ABSTRACT:

The main goal of this study is to describe factors associated with trends over time in the incidence and survival rates following hospital admission for acute myocardial infarction (MI). Data have been collected during thirteen 1-year periods beginning in 1975 and extending through 2001 on all MI patients admitted to hospitals in the Worcester, Massachusetts, Standard Metropolitan Statistical Area.

5-3 Final Project Part II Milestone Three: Process and Calculations | |

Instructions | |

In order to successfully explore the health question, you need to plan what tests you need to run. In Milestone Three, you will create a table in which you propose the calculations and graphs you will need to perform to answer the health question you are investigating. Then explain why you chose these calculations to explore your health question. To complete this assignment, review the Milestone Three Guidelines and Rubric document. |

IHP 525 Milestone Three Guidelines and Rubric

Overview: Your task is to help the organization answer the health question by critically analyzing the data. You will run statistical tests, interpret the results, and present the results and recommendations to non-technical decision makers in the form of a statistical report. Keep in mind that it is your job to do this from a statistical standpoint. Be sure to justify your conclusions and recommendations with appropriate statistical support

Prompt: In order to successfully explore the health question, you need to plan what tests you need to run. In Milestone Three, you will create a table in which you propose the calculations and graphs you will need to perform to answer the health question you are investigating. In crafting your table, consider the following:

Watch Choosing a Statistical Test (12:31).

What tests will you need to run?

If you are hypothesis testing, what are your null and alternative hypotheses?

Are there any tests that you want to use that you have not learned about yet? What are t Specifically address this critical element: hey? What is your plan for researching these tests.

Then explain why you chose these calculations to explore your health question.

Process: Propose how you will go about answering the health question you were asked to address based on the data set provided

7-2 Final Project Part II Milestone Four: Data Analysis | |

Instructions | |

In Milestone Three, you created a table listing the tests you were going to complete to investigate your health question. In Milestone Four, you will actually complete these calculations. To complete this assignment, review the Milestone Four Guidelines and Rubric document. |

IHP 525 Milestone Four Guidelines and Rubric

Overview: Your task is to help the organization answer their question by critically analyzing the data. You will run statistical tests, interpret the results, and present the results and recommendations to non-technical decision makers in the form of a statistical report. Keep in mind that it is your job to do this from a statistical standpoint. Be sure to justify your conclusions and recommendations with appropriate statistical support.

Prompt: In Milestone Three, you created a table listing the tests you were going to complete to investigate your health question. In Milestone Four, you will actually complete these calculations.

Specifically, you must address these critical elements:

A. Graphs: In this section, you will use graphical displays to examine the data and formulate an initial hypothesis. In particular, you should:

1. Create key graphical displays that give a sense of potential relationships between variables. Include the graphs and discuss why you selected these graphical displays as opposed to others.

B. Conduct appropriate hypothesis tests, simple regressions, and other tests to analyze the data set.

C. Explain why these tests are the best choice in this context and how they compare with established best practices.

D. Analysis of Biostatistics: Use this section to describe your findings from a statistical standpoint. Be sure to:

1. Present key biostatistics from the graphs, tests, and regressions performed, and explain what they mean. Be sure to include a spreadsheet showing your work as an appendix.

2. What statistical inferences or conclusions can you draw based on the hypothesis tests and simple regression analyses performed? Justify your response

Guidelines for Submission: You will submit screenshots of the graphs, the completed table from Milestone Three, and 2–4 paragraphs explaining and interpreting these items in a single Microsoft Word document with double spacing, 12-point Times New Roman font, one-inch margins, and using APA format for any citations.
