In Milestone Three, you completed a table listing the statistics you were going to complete to investigate your health question. In Milestone Four, you will actually complete these calculations.

Attached below is rubric and milestone 3

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 descriptive statistics and a statistical test, create a graph, interpret the results, and present the results and recommendations to non-technical decision makers in the form of a data analysis. 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 statistics 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:

I. Data Analysis A. Graphs: In this section, you will use graphical displays to examine the data.

1. Create at least one graph that gives a sense of the potential relationship between the two variables that form your chosen health question. Include the graph and discuss why you selected it as opposed to others.

B. Conduct an appropriate statistical test to answer your health question. C. Explain why this test is the best choice in this context. D. Analysis of Biostatistics: Use this section to describe your findings from a statistical standpoint. Be sure to:

1. Present key biostatistics from the graph(s) and statistical test and explain what they mean. Be sure to include a spreadsheet showing your work or a copy of your StatCrunch output as an appendix.

2. What statistical inferences or conclusions can you draw based on the results of your statistical test, descriptive statistics and graph? Justify your response.

Rubric 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.

## IHP 525 Milestone Three Table

For this milestone, in order to explore your health question you are investigating, you need to plan what descriptive statistics and statistical test you will need to run, as well as what graph you will need to create.

Step 1: Complete the table below in which you will propose the calculations and graph(s) you will need to perform to answer the health question you are investigating.

Solution

Independent samples t-test can be used in a case where the dependent variable is quantitative and the independent variable is categorical with 2 groups. The mean of number of days spent in hospital (LOS) will be calculated for both groups (males and females) in order to enable computation of the differences. The standard deviation is also calculated for both male and females’ length of stay. The t-statistics will be calculated using the formula given in the table where x-bars and s represents the calculated means and standard deviations for both groups. The critical value of t will be calculated to help in decision making. The degrees of freedom will be calculated to enable determining the critical value. The p-value will also be determined. All these calculations will help in determining whether the null hypothesis will be rejected or not. A bar graph will be computed which enables visual representation of the differences of the two groups (males and females) at a glance.
