Identify the five-number summary of the following data set. 7, 11, 21, 28, 32, 33, 37, 43.

Solution:

We have to find the five number summary of the data set.

The data given is in ascending order 7, 11, 21, 28, 32, 33, 37, 43.

1) Minimum = 7

2) Q₁ = (11 + 21)/2

= 32/2

= 16

3) Median = (28 + 32)/2 = 60/2 = 30

4) Q₃ = (33 + 37)/2

= 70/3

= 35

5) Maximum = 43

Therefore, the five number summaries are 7, 16, 30, 35 and 43.

Identify the five-number summary of the following data set. 7, 11, 21, 28, 32, 33, 37, 43.

Summary:

The five-number summary of the following data set. 7, 11, 21, 28, 32, 33, 37, 43 are 7, 16, 30, 35 and 43.
