Concept explainers
To make:
Box-and-whisker plot of the given monthly average high temperatures (in degree Fahrenheit) for Atlanta, Georgia.

Explanation of Solution
Given:
Numbers of participants in twelve community service days sponsored by a school.
Calculation:
First of all, we will arrange our given data in ascending order as:
Now we will find the median of the data. Since our data have an even number of data points, so median will be average of two middle values as:
Now we will find the 1st quartile. 1st quartile will be median of 1st half.
The upper quartile will be median of 2nd half.
We will make two whiskers for minimum value (53) and maximum value (89).
Upon using our given data, we will get our required box-and-whisker plot as shown below:
