Question
A researcher wants to study the academic performance of suburban secondary schools in his county. He decides to measure each school's academic performance by collecting data on the percentage of students passing at least one Advanced Placement (AP) exam. The following table shows each school with the percentage of students passing at least one Advanced Placement (AP) exam. No. 1 2 3 4 5 6 7 00 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 School Booker T.

If he lists all possible scores individually, the frequency distribution table would have rows. The researcher decides that a grouped frequency table would better organize this data.
