Question

Construct a box-and-whisker graph using the following data:

87, 94, 82, 78, 95, 91, 87, 83, 101, 83, 82, 77, 80, 102, 75

Answer 1

data given: {87, 94, 82, 78, 95, 91, 87, 83, 101, 83, 82, 77, 80, 102, 75}

arrange in ascending order:

75, 77, 78, 80, 82, 82, 83, 83, 87, 87, 91, 94, 95, 101, 102

Identify:

• Q1 = 80

• Q2 = 83

• Q3 = 94

• IQR = 14

• Median = 83
