M.O.5.5.4

Collect and analyze data using mean, median and mode to

determine the best statistical measure.

Guiding Questions

• What is mean, median, and mode?• How do you calculate mean,

median, and mode?

Materials

• Nine index cards with numbers on them

• Computer• Power Point Lesson Plan

VOCABULARY

• Data: Collected information • Mean: The number found by adding all
