Announcements
- Lab 3
- “1 - unit increase” for categorical variables is WRONG
- We are comparing the mean IAT score for different categories
- Still a couple students with factor issues in main variable
- Make sure to use
fct_relevel to change the order of the categories
- Example:
fatal_dep = fatal_dep %>% mutate(Fatalism = fct_relevel(Fatalism, "Low", "Medium", "High"))
- Ordering with
as.order or ordered will mess up your regression (example)
- Quiz 2 scores up
- I will be posting the poster instructions TONIGHT!
- HW 5 will be optional (see homework page)
- Anything else?
