Get two activities with one instructional activity. The first instructional activity, is appropriate for grades 6-12 and takes about 20 minutes. It introduces the concept of measures of central tendency, primarily the mean, and discusses its uses as well as its limitations. The second activity, is geared more for grades 9-12, and highlights the concept of variability and spread of data via standard deviation. Both activities are relatively simple, but the directed discussion questions add some pizzaz to its overall appeal. Included are suggestions for assessment and extensions.
