Answer Key

1)

Least value = 2

Lower Quartile (Q1) = 7

Median (Q2) = 9

Upper Quartile (Q3) = 10

Highest value = 13

2)

Least value = 23

Lower Quartile (Q1) = 30

Median (Q2) = 32

Upper Quartile (Q3) = 34

Highest value = 45

3) 

Least value = 60

Lower Quartile (Q1) = 81 

Median (Q2) = 100

Upper Quartile (Q3) = 110

Highest value = 170

4) 

Range = largest value - smallest value

3.7 = 5.4 - x

x = 1.7

Smallest value = 1.7

5)

Range = largest value - smallest value

20 = x - 6

x = 26

Largest value = 26

Interquartile Range = Upper Quartile - Lower Quartile

5 = 16 - x

x = 11

Lower Quartile = 11

6)

Range = largest value - smallest value

70 = 160 - x

x = 90

Smallest value = 90

Interquartile Range = Upper Quartile - Lower Quartile

25 = x - 115

x = 140

Upper Quartile = 140
