Mr. Hamilton's class at Manorville High School has established e-mail contact with a high school class in Osaka, Japan. The two groups of students begin by gathering and sharing information about their classes. They exchange data about the number of people in each student's family, about how far each student lives from the school, and about the number and type of pets each student has. The Japanese students have heard that houses and apartments in North Americaare very large, and they want to compare the living areas of the students in Manorville with their own. Each class makes a list of the floor areas in their families' houses or apartments. They compute the mean, the median, the mode, the range, and the standard deviation for their data and share them electronically.
