A fun, hands-on activity spanning 3-4 days that covers Data Organization (Tally Charts and Tables), Graphing (Histogram, Pareto Chart, and Time-Series Graph), and Central Tendency. Students will be conducting an experiment with pennies as the detectives on the case. Working with partners, they will be analyzing their penny sample to determine if the bank robbers from a cold case are at it again! Examples of each graph are given and the activity is suitable for many different ability levels.
