Exercise

Recode a variable

The cls_students variable in evals tells you the number of students in the class. Suppose instead of the exact number of students, you're interested in whether the class is

"small" (18 students or fewer),
"midsize" (19 - 59 students), or
"large" (60 students or more).

Recode the cls_students variable into a new variable, cls_type, using case_when(). This new variable should have three levels as described above. Save the resulting data frame (with the new variable) as evals.
