**Editor's notes**

This is a project based on Benford's law. I had this idea after watching the Numberphile series on YouTube. This is a project based activity that involves many skills including working with large numbers, using percentages, representing data and probability.

The investigation is introduced to learners using the PPT (and optional YouTube links). Learners then split into four groups - each is given a random set of share prices [see Excel file]. Each group investigates the occurrence of numbers starting with each digit from 1 to 9.
