# 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)
