For each of the following data sets, use your calculator to help find the interquartile range and the
population standard deviation. Show your calculation for the IQR. Round all non-integer values to the
nearest tenth.
(a) 4, 6, 8, 10, 15, 19.22, 25
(b) 3.3,4,5,5,6,6,7,7,8

(PART A)

Range: 21

(IQR) Interquartile range: 3.22

(PART B)

Range: 4.7

(IQR) Interquartile range: 2.5

Step-by-step explanation:

For (A):

4, 6, 8, 10, 15, 9.22, 25

Median: 10

Lower Quartile(Q1): 6

Upper Quartile(Q2): 9.22

(IQR) Interquartile range: 9.22 - 6 = 3.22

Range: 25 - 4 = 21

For (B):

3.3, 4, 5, 5, 6, 6, 7, 7, 8

Median: 6

Lower Quartile (Q1): 4.5

Upper Quartile (Q2): 7

(IQR) Interquartile range: 7 - 4.5 = 2.5

Range: 8 - 3.3 = 4.7
