Instructions
Complete the following exercises related to box and whisker plots. Show all calculations where necessary.
1. Understanding Box and Whisker Plots
Define what a box and whisker plot is and what information it displays.
2. Create a Box and Whisker Plot
The following data represents the scores out of 100 of a group of students on a math test:
- 78
- 85
- 90
- 70
- 88
- 92
- 81
- 95
- 87
- 75
Find the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.
Minimum: ________
Q1: ________
Median (Q2): ________
Q3: ________
Maximum: ________
3. Drawing the Box and Whisker Plot
Using the information from the previous question, draw the box and whisker plot in the space below. Make sure to label the quartiles and the minimum and maximum values.
4. Analyzing the Box and Whisker Plot
What does the box and whisker plot tell you about the distribution of the scores? Discuss any observations you can make about the data.
5. Comparison
How would you compare the mean score versus the median score for the data set? Why is this comparison important?
