LESSON TITLE: Exploring Central Tendency

CURRICULUM AREA: Math

GRADE LEVEL: 6-8

ESSENTIAL QUESTION:

What is the mode, median, mean, and range for player height of given ACC team?

ACTIVITY SUMMARY:

Students will find measures of central tendency for player height of a given team. Students will explain how mean is sensitive to extremes and explain its use in comparison with median and mode.

ACTIVATING STRATEGIES:

Review meaning of mode, mean, median, and range and review method for finding each measure. Predict measures.

METHODS:

  • 1.

    Separate students into groups, so each ACC school is represented. (Teacher may choose to use one school as an example to model.)

  • 2.

    Students work cooperatively, using fact sheet and resources to find measures of central tendency.

  • 3.

    Students organize gathered data on a chart.

  • 4.

    Students generate questions and answers based on the chart.

SUMMARY STRATEGIES:

Which measure of central tendency is most appropriate for your data? Why? Which measure is most misleading? Why?

RESOURCES:

Data on player height for each ACC team from team rosters. (Teacher can gather player data from ACC.com before class or students can gather data using computer access)
