"Clean the data!" "I did not know it was dirty." Introduce your class to the process of cleaning data so that it can analyze it. Groups work through a guide that demonstrates the common ways to filter and sort data. Pairs then discover that they need to summarize some data in a subjective way in order to analyze it. The activity builds critical thinking skills.
