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.
|
Question: |
Answer: |
|
What is your health (research) question? |
Does gender have an effect on the cholesterol level of diabetics? |
|
What is the corresponding null and alternative hypotheses? |
Null hypothesis: there is no difference in cholesterol levels in diabetics between genders. Alternative hypothesis: there is a difference in cholesterol levels in diabetics between genders. |
|
List the descriptive statistics you will compute, using which variable(s), to help answer your health question. |
Mean Standard Deviation Median Range Min Max Q1 Q3 |
|
What is the name of the statistical test that you will use to test your hypothesis and answer your health question? |
Two-sample/independent t-test |
|
What is the formula for your chosen statistical test? |
|
|
Why is the statistical test you chose appropriate to answer your health question? Be sure to be clear on how the two variables you described in Milestone Two are used to complete this test. |
I will share this answer later. |
|
Which graph(s) (histogram, stem and leaf, boxplot, bar graph, scatterplot) will you use to visualize the answer to your health question? Be specific and include which variables will be used and if the graph will be created for different subgroups of subjects. |
I will do side by side box plots as the two groups: males and females will be on the same metric. This will allow me to visualize the quartiles along with outliers. Data with severe outliers may not be normally distributed and a normal distribution is needed for the two-sample/independent t-test. |
Step 2: Provide a 1-2 paragraph explanation below as to why you chose the calculations outlined in the table above to explore your health question. Describe what statistics you will compute in order to answer your chosen health (research) question. Be sure to discuss any graphs that you will compute and what information they will provide to help you answer your health question. I will share my answer later.
