A very well thought out worksheet on how to draw a box and whisker plot with step by step instructions. The worksheet is very easy to read and comprehend. The steps to creating a box and whisker plot were broken down nicely into simple steps with easy to understand terms. I could easily give this to a substitute and the students should have no problem completing the activity.
Suggestions for enhancement:
• Create an answer key. This might be helpful to teachers that are not comfortable with the concepts of Box and Whisker Plots.
• Create a lesson plan. The worksheet is great to show the ‘how’ of a box and whisker plot, but a lesson plan detailing a discussion about the ‘why’s’ and ‘what’s’ of a box and whisker plot. Why is there a box? What is significant about the box? Why are there whiskers? What is the significance of the whiskers? Also a lesson plan that covers percentiles would fit perfectly with the plots. The students could learn about the 25th percentile, 50th percentile, and 75th percentile and how they are represented in a box and whisker plot.
• Extend using real-world data. Pick a favorite/local athletic team and use the season’s scores to make a plot. Or you could use the stock market, the heights of the student’s, etc.
• Extend to more statistics. Since the prerequisite is the ability to find the median, I am assuming they also know how to find the mean, mode, and range. This can then be extended to histograms, scatter plots, standard deviation, etc.
