Box and Whiskers

$0.00

Box and Whiskers graphs are a simple, linear way to analyze sets of continuous numerical data. They are especially helpful in determining whether or not there are significant differences between sets of data.  A box-and-whiskers shows the distribution of data along a number line.  There are four components to a box and whisker plot: two whiskers and two boxes.  Each component makes up 25% of the data regardless of how big or how small it is.

Description

Box and Whiskers graphs are a simple, linear way to analyze sets of continuous numerical data. They are especially helpful in determining whether or not there are significant differences between sets of data.  A box-and-whiskers shows the distribution of data along a number line.  There are four components to a box and whisker plot: two whiskers and two boxes.  Each component makes up 25% of the data regardless of how big or how small it is.

Classroom Procedure:

  1. Begin by explaining to students that there are a lots of ways to display numerical data.
  2. While reading the content pages, reinforce how to find a median and give students additional examples of five-number summary problems in order to help them practice.  Use the additional resources to enhance understanding.
  3. Introduce the notes on box and whiskers. Have students practice using data to create box and whisker plots.  Use the additional resources to enhance understanding.
  4. Have students practice problems with a partner.
  5. Follow Activity page with students. Have students work individually.  Follow the directions on the activity pages to collect data as a class and create the box and whisker plots.
  6. Distribute Practice page. Check and review the students’ responses as a class.
  7. Distribute the Homework page. Have students discuss their findings at the beginning of the next class.
  8. In closing, ask students to explain how to find each data piece in a five-number summary.
  9. Allow for responses and discussion
