It would be interesting to do the same exercise using classical British (not Customary) units viz feet and inches and stones and pounds. In addition to calculating BMI, calculate the correlation between weight(or mass) and height. BTW, I would expect to see the mean and standard deviations of height in feet and inches (not decimals of a foot) and weight (or mass) in stones and pounds, not decimals of a stone.
BTW, if any US readers are confused by stones, there are 14 pounds in a stone (or as one joker put it, 14 pebbles in a stone).

I would measure the students heights in meters, then get their mass in kilograms (using a Borg bathroom scale) and then Excel would take the mass and divide by the heights squared. Since retiring from Chicago City Colleges, I have not been able to do this with a class, but it seems like the type of assignment most math teachers could do and students would at least learn how high they are in meters and learn their mass in kilograms.

After measuring height (the device had both in and cm) and weight (display was in lb only), the woman had to consult a chart to find out my BMI. I already knew my mass in kg and my height (1.79 m) so I just took out my iPhone, went to Utilities/Calculator, entered in the kg, divided by 1.79, divided by 1.79 again, and gave her the answer before she got it from the chart. I told her if you measure people properly the calculations are easy.
