This lesson was created to help students with the Edexcel level 3 examination. Students learn the formula for the geometric mean and look at some worked examples.

I bought this resource because it was the only resource on TES about Geometric Mean. It contains a very basic definition (freely available on many websites such as YouTube, Mathsisfun, etc) and then 1 example which is useful. The Index Numbers section wasn't relevant to me but may be similarly useful to people. I'd have been happier if it had contained more examples.
