Student Learning outcome: Use the Five-Number Summary to Create a Boxplot to Describe a Data Set
In this activity, you will investigate the relationship between boxplot shapes and the corresponding five-number summary.Step 1. Review
Review the learning resources for this lesson before studying the case problem.
Step 2. Analyze
Analyze the case problem below.
The accompanying figure shows four boxplots labeled A to D. Also given are four five-number summaries, labeled I to IV. Match each five-number summary to the appropriate boxplot. Note that scales are not included on the boxplots, so you will have to consider what the five-number summary implies about the characteristics of the boxplot.

Step 3. Respond
Respond to the case problem by showing the boxplot properties, logic steps, and reasoning you used to match each figure with its corresponding five-number summary.
Step 4. Share
To share your work, access to the first post below and click on the “Reply” button under this post and paste your work into the “Message” box. Make sure to reference others’ intellectual property when necessary. All references should follow 7th Edition APA formatting. For further instructions, see the resource on the Himmelfarb Health Sciences Library: APA citation resource (N.B. references are excluded from word counts).
Step 5: Interact
To complete the activity, you will need to reply to at least two posts by your peers respectfully and professionally. Ensure that your post engages your peers' ideas by including a reflection on their comments, sharing ideas of other potential difficulties and parties involved, or asking thought-provoking questions. If a peer comments on your posting, please reply. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “post to the forum.”
