Question

A group of students were asked to guess the width of the room in feet, measured to the nearest foot (1 meter = 3.28 feet, to 2 decimal places). Construct a back to back stemplot from these two datasets. How will you overcome the problem that different units are used in the two datasets?

Answer 1

I think the only way to properly create a back to back stem plot here is to convert meters to feet or feet to meters. The conversion is 1 ft = 12 in = 30.48 cm = .3048 meters. Since this is a guesstimate, you could also say that a foot is about 1/3 of a meter, and divide all feet values by 3. Then create a back to back with the new values, rounded to nearest whole number. Hope this helps
