Chapter 14.3, Problem 27E

To determine

To make the box whisker plot of the data of students attending the school in the country and discuss the variability of data.

Explanation of Solution

Consider the following data set of students attending the schools are given by table-

School Name	Number of Students
School 1	87
School 2	52
School 3	91
School 4	66
School 5	79
School 6	56
School 7	73
School 8	90
School 9	78
School 10	51
School 11	83

The given data set is $87,52,91,66,79,56,73,90,78,51,83$ .

Now, let us make the following box-whisker plot of the data set as follows-

  

The variability of data set is as follows-

Minimum: $51.$ ,Maximum: $91$ ,median is $78$ ., $Q_1=56$ and $Q_3=87$ .
