Put the numbers in order from smallest to largest:

15, 19, 20, 25, 25, 28, 29, 30, 35, 37, 38, 43


Part A:

minimum = 15

maximum = 43

Q1 = (25+20) /2 = 45/2 =22.5

Q2= (28+29) /2 = 57/2 = 28.5

Q3 = (35+37)/2 = 72/2 = 36



Part B:  Range = Maximum - minimum = 43-15 = 28

C: IQR = Q3 - Q1 = 36 - 22.5 = 13.5
