To find the number of days each student is absent, Group By should be selected for StudentID, and Count for DateAbsent. This will allow us to count how many times each student was absent, rather than finding the average number of days absent for each grade. Grouping by StudentName will not be helpful in determining who was absent on a particular day, as multiple students can have the same name. Grouping by both DateAbsent and StudentID will not give us the number of students absent in a particular grade on a given day.
