How big is a Cubit? - Old Style Measurement

In week 6 we continued looking into Measurement.  Long before the rulers that we have come to know with their mm, cm and m standard measurements came about, the Egyptians used their own standard measurements.
Cubits, Foot, Digit and Hand span lengths were used.  How did they standardise it?  They used the cubit, foot, digit and hand span of their Pharaoh.  Hopefully their Pharaoh didn't change too often.

We investigated the range of cubits, hand spans, feet and digits of our classmates.  Then we sorted them to find our most common length (mode), our median length, the range of lengths and the class averages for each of these measurements.
