Notes from me and the TAs

  • Using ANY_HARDSHIP or MULT_HARDSHIPS
    • If you look at the User Guide, this involves information from food security
    • We need to adapt the variable to exclude food security: use case_when() to construct it
  • Using “Survey Questions”
    • Be very careful of this!
  • Activity 2.9: List any categorical variables that have less than 100 observations in a group
    • Not the number of observations for an entire variable, but check each level/group of the variable!
  • Do not use multiple variables that capture the same information
    • Example: PPINCIMP and FPL50_100
  • Do NOT use variables that are measuring missing data unless you are interested in how missingness is related to the outcome
    • Example: FAMSIZE_MISS, NUM_CHILD_HH_MISS
  • The TAs left comments in the rubric! Please look at them!

A note on the “Survey Questions”

  • I said not to use the variables under this, but you can if you found one to be very interesting
  • You just need to be extra cautious using these because they are not as nicely packaged/processed
  • And some of them go into other variables!!
    • Like UNMETCARE_Y already includes the survey questions about health care
  • Some of the variable have A LOT of missing data

Get into groups of 2-4

  • No more than 4!
  • Introduce yourself if you do not know each other
  • Share you html documents with each other (email, airdrop, etc.)
06:00

Introduce Research Question

  • Share your research question with each other!
    • Should be using the same outcome + your main variable
  • Share your other variables
  • Is everyone using the appropriate variables?
  • Did anyone see any potential issues with how many individuals are in each category of a variable?

 

  • If time, did anyone want to use ANY_HARDSHIP or MULT_HARDSHIPS? How would you construct these variables?
15:00

Double check code and saved data

  • Did everyone in the group successfully save the dataset?
  • Can you open it right now?
05:00

Compiled introductions

  • What major points did you include in your introduction?
  • Would you change anything after discussing with your group?
