FINAL EXAM: R Programming (code only)

In this part of the final exam, you will be asked some specific questions about coding in R. Here are the specific skills you should have before attempting this part of the exam:

1. Selecting the appropriate type of regression model (linear, binary logistic, or ordinal logistic)

2. Transforming ordinal variables to ordered factors as dependent variables for ordinal logistic regression

3. Installing and calling libraries (so you can use commands in them)

4. Programming regression model calls (linear, binary logistic, or ordinal logistic regressions)

5. Generating code that will create R-squared, pseudo R-squared, or adjusted R-squared values

6. Generating code that will create factor change coefficients for logistic regressions

7. Know what dependent, independent, and control variables are and where they show up in the code

8. Know levels of measurement

9. Create a new variable by creating a formula using other variables (such as adding, multiplying, subtracting, etc.)

10. Resolve very basic, very common errors

Note that this part of the exam does NOT require you to run R on your own computer, only how to program in R. 

This part of the exam has 6 questions. Questions require you to write short snippets of code (generally between one and 5 lines of code). Two questions ask you to resolve very basic, common errors. You have 180 minutes to complete this open note, open book, open internet, closed people (live chat and forum posts are not ok; pre-existing forums are ok). This part of the exam should take you nowhere near the time limit.
