Students often view collected data as only a list of numbers and fail to recognize that when summarized, collectively, they provide useful information for decision-making. An activity that gives students an opportunity to visualize data through various graphs and charts, and to explore and compare different shapes of distributions will be described. This activity also allows them to explore three important properties of measurement: validity, reliability, and unbiasedness. Outcomes show that this activity encouraged students to communicate the behavior of data, both orally and in writing, using non-technical terms, both statistically and in the context of the scenario being analyzed.
