This online activity offers students a chance to compare soda prices from two stores using data displayed on a scatter plot graph. Students are shown how the line y = x can be used to analyze the data and draw a conclusion. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The activity contains a solution hint, two different ways to find the solution, questions related to analyzing similar data from other fields, and family activities using data collected in the home.
