Students explore ways to model the relationship between variables as they get to know a fictional Room 204 and their own classmates. They look at survey data for Room 204 to design their own survey questions to analyze and represent. Students represent these relationships in bar graphs, point graphs, and measures of central tendency (mean and mode). Students then make generalizations and predictions.
