Question

Calculate the five-number summary of the following data set: 21, 27, 30, 22, 28, 20, 28, 19, 28, 22.

a) Min = 19, Q1 = 21, Median = 26, Q3 = 28, Max = 30
b) Min = 19, Q1 = 22, Median = 28, Q3 = 30, Max = 31
c) Min = 20, Q1 = 22, Median = 27, Q3 = 28, Max = 30
d) Min = 19, Q1 = 21, Median = 28, Q3 = 29, Max = 30

Answer 1

The five-number summary of the given data set is Min = 19, Q1 = 21, Median = 27, Q3 = 28, Max = 30.

Step-by-step explanation:

The five-number summary of the given data set is as follows:

• Minimum (Min) = 19
• First Quartile (Q1) = 21
• Median = 27
• Third Quartile (Q3) = 28
• Maximum (Max) = 30
