EPIB315 - Final Project

For your final project, the following is a small dataset collected from graduate students at a large

mid-Atlantic university:

ID Number 1 2 3 4 5 6 7 8 9 10

Age 28 22 44 21 22 25 33 32 25 27

Race/Ethnicity 1 2 1 0 2 1 2 0 0 2

Gender 0 0 1 1 1 0 0 0 1 1

Degree Program 0 0 2 2 2 0 0 0 1 2

Depression 21 16 18 9 4 28 31 12 16 19

Alcohol Use 3 2 1 0 0 2 4 0 2 3

Coffee Use 4 3 5 3 0 8 4 1 4 5

Coding is as follows:

ID Number: (Assigned ID number)

Age: (Age in years)

Race/Ethnicity: (0=Asian, 1=Black, 2=White)

Gender: (0=Female, 1=Male)

Degree Program: (0=Master of Public Health, 1=Master of Science, 2=Doctorate of Philosophy)

Depression: (Scale from 0 to 40)

Alcohol Use: (Average number of drinks per week)

Coffee Use: (Average number of drinks per week)

For this project, you will write a maximum 1 page report in a word document (.doc, .docx).

Format must be 12 point Times New Roman, single space. If formatting limits are not adhered

to, there will be a grade penalty. Note that these limits do not include calculations, all

calculations (either by hand or using statistical software) are submitted in the same document

after your report. If conducting analyses using statistical software, screenshots of your output are

considered calculations. You can copy and paste screenshots of your calculations into the

same word document, after your report. Do not attempt to submit two separate documents.

You must show all calculations, otherwise you cannot receive full credit. Work independently,

this is not a group project. The following are the guidelines (and scoring) for the content of

your report:

1. Select three exposures you are interested in from the dataset above. Test if each of these

exposures is associated with an outcome of your choice. For each of your three tests, describe all

hypothesis testing steps. (120 points)

2. Based on both your understanding of these variables and the data provided, describe if any of

the variables might be confounders of any of the associations tested above, and why. (30 points)

3. What variables not listed here would you like to have included as possible confounders? Why?

(30 points)

4. Other than confounding, what are two additional limitations that may present issues in

interpreting results? (20 points)
