Understanding Box and Whisker Plots

This video tutorial from Mumu Math and Science explains how to read and understand box plots, also known as box and whisker plots. It covers the components of a box plot, such as the median, lower and upper extremes, and quartiles. The video provides examples of analyzing data using box plots, including calculating the range and identifying test scores. The tutorial concludes with a prompt to subscribe for more math and science videos.

What is the primary purpose of a box and whisker plot?

• To show the correlation between two variables

• To calculate the average of a data set

• To visualize the distribution of a data set

• To display the frequency of data points

Which part of a box plot represents the median?

• The lower extreme

• The upper extreme

• The upper quartile

• The middle quartile

In a box plot, what do the lower and upper extremes represent?

• The range of the data

• The quartiles

• The minimum and maximum values

• The average values

How do you calculate the range in a box plot?

• Subtract the lower quartile from the upper quartile

• Subtract the lower extreme from the upper extreme

• Add the lower and upper extremes

• Add the lower and upper quartiles

In the first example, what is the lowest test score?

• 35

• 99

• 82

• 60

In the first example, what is the highest test score?

• 60

• 82

• 99

• 35

In the second example, what is the median of the data set?

• 60

• 35

• 50

• 10

In the second example, what is the range of the data set?

• 50

• 60

• 35

• 10

What is the median of the lower quartile in the second example?

• 10

• 20

• 50

• 35

What is the median of the upper quartile in the second example?

• 35

• 20

• 50

• 10
