When the data arrive from their Japanese friends, Mr. Hamilton's students realize that they will have to do a bit more work before a comparison can be made. It has not occurred to them that the information from the Japanese students would be reported in square meters whereas all their measurements are recorded as square feet. At first Angela thinks that they will need to get the original data about the Japanese room sizes, convert the measurements to feet, and recompute the size of each living area before they can determine the statistics. Shanika points out that a spreadsheet would do the conversions quickly but thinks that they will still have to ask for the original data. Mr. Hamilton suggests that before asking the Japanese students to enter all those extra data, they might work with the summary statistics they have and see if they can find a way to compare them directly with their own.
