Episode 2: Statistical sampling in archaeology

In this episode we interviewed Alison Atkin from the University of Sheffield about her work as an archaeology PhD student, and how she uses statistical sampling to gather data about victims of the plague.

Puzzle: A field is 6 metres square. Your sampling methodology dictates you should excavate 30% of the field. What would be the side length of a square trench which covers 30% of the area?

Solution:

The area of a field 6 metres square would be 6 x 6 = 36 square metres. 30% of this area would be 36 x 0.3 = 10.8 square metres, which would be covered by a square trench whose side length is the square root of 10.8. This is approximately 3.29 metres (to the nearest centimetre).
