Naomi Wiggins · Answer 1

Mid term:

Q1 = (88 + 85) / 2 = 86.5

Q2 = (92 + 95) / 2 = 93.5

Q3 = 100

IQR = Q3 - Q1 = 100 - 86.5 = 13.5

final exams:

Q1 = (65 + 78) / 2 = 71.5

Q2 = (88 + 82) / 2 = 85

Q3 = (95 + 93) / 2 = 94

IQR = Q3 - Q1 = 94 - 71.5 = 22.5

so the final exams has the largest IQR
