Your Turn

  1. Create a new variable called pct that shows each race/ethnicity as a percentage of all students in each district. This will require two steps.

  2. You'll need to use group_by() and summarize() to calculate the number of students in each race/ethnicity group in each district.

  3. You’ll need to use group_by() and mutate() to calculate the percentage of students in each race/ethnicity group in each district.

Don’t forget to ungroup() at the end of each step. Use this code to get started:

Daniel Carter has a nice walkthrough of using group_by() and mutate().

If you forget to ungroup() every once in a while, you’re joining an illustrious group.

Need a cheery reminder to use ungroup()? Here you go!
