McREL Standards Activity


Data Shuffle


Purpose:As a result of this activity, students will be able to recognize that data can be presented in different ways that convey different messages.

Mathematics
 Standard 6.Understands and applies basic and advanced concepts of statistics and data analysis
   Level III [Grade 6-8]
   Benchmark 8. Understands that the same set of data can be represented using a variety of tables, graphs, and symbols and that different modes of representation often convey different messages (e.g., variation in scale can alter a visual message)
Student Product:Graphic display of data, Report comparing displays
Material & Resources:Graphs from newspapers, magazines, or advertisements
Teacher's Note:The graphs can either be provided for the students, or the students may be required to find graphs on their own to bring to class
Activity
In a newspaper, magazine, or other source, each student is to find an advertisement or persuasive article that uses charts or graphs to present data. Materials should be chosen that contain sufficient information to construct graphs with a different format and/or scale. Each student is then to create a new display using the same information but altering the format or scale to communicate a completely different message. Students should write a comparison of the two displays and evaluate why the advertisers chose the format they did (i.e., what message were they trying to convey through their choices).
