Question

Transcribed Image Text: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.

(Note: Academic Performance is measured as the percentage of students passing at least one AP exam)
In order to organize the data in Table 1, the researcher needs to decide whether to use a grouped frequency distribution table or whether to list each
possible score individually from the lowest score to the highest score (or from the highest score to the lowest score), including scores in between that
have zero frequencies. 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.

Transcribed Image Text:Table 2 divides the range of these 25 schools' academic performance into nine intervals and gives some of their frequencies and relative frequencies.
Based on the information provided in Table 1, use the dropdown menus to complete Table 2.
