Rubric

  1. (1 p) Is there a topic of interest?

  2. (2 p) Are the variables relevant to a set of research questions?

  3. (4 p) Are there at least 2 categorical and 2 numerical variables (at least 4 “data” variables)?

    • 1 categorical variable with only 2 levels
    • 1 categorical variable with at least 3 levels
    • 2 numerical variables with many possible unique values
    • More variables are welcome and you’re likely to add to this later in the semester
  4. (3 p) For each variable, is there a variable description, a data type, and coded value descriptions?

  5. Compile this Rmd file to an html, print/save to pdf, and upload to UNM Learn.


Using the NESARC dataset, choose from among the variables listed at the bottom. I selected this list of about 150 to narrow your attention from among the 3008 variables in the NESARC dataset. This is the beginning of your investigation toward answering a few questions that you’ll pursue throughout the semester.

I recommend this strategy:

  1. Save the NESARC codebook to your computer: https://statacumen.com/teach/ADA1/PDS_data/NESARC_W1_CodeBook.pdf
  2. Review the list of variables at the bottom of this document, referring to the codebook for more information as required.
  3. Find a set of variables that are of some interest to you that are around a theme.
    • Make sure you satisfy the “at least 2 categorical and 2 numerical variables” requirement in the Rubric.
  4. Develop a few research questions that relate pairs of these variables: “Does A relate to B?”
  5. Define a topic that synthesizes the research questions; my example is about an “association between nicotine dependence and number of cigarettes smoked.”
  6. Complete your Codebook after you are happy with your research questions and topic.
  7. Refer to the Rubric and “grade yourself” by making sure you satisfy all of the components of the assignment.

Your codebook may continue to develop throughout the semester.

Topic and research questions

Topic:

As you select variables from the bottom of this document, a general topic should reveal itself to you.

The relationship between depression and drinking (beer).

Research questions:

  1. Does going to a counselor for depression (DepressionCounselor) predict the number of beers when you drink (NumBeersConsumed)?

  2. Question 2

  3. Question 3
