With data series: (20, 22, 30, 23, 28, 25, 24, 25, 23, 21, 23) Construct a Box Diagram.

Homework Answers

Answer #1

For constructing a box diagram we need to find 5-number summary statistics.

Minimum, First quartile (Q1) , Median , Third quartile ( Q3), Maximum.

Minimum = 20

First quartile = 22.5

( Using excel =QUARTILE(Select values,1))

Median is middlemost value when data is in increasing order.

20 21 22 23 23 23 24 25 25 28 30

Median = 23

Third quartile = Q3 = 25

( Using excel =QUARTILE(Select values,3))

Maximum = 30
