This is very similar to the excellent activity from danielabbott89 - https://www.tes.com/teaching-resource/mean-from-a-frequency-table-amazon-reviews-6323431
However, the products in that resource are now a bit out of date, so I wanted to make a resource that would have a bit more longevity. Students have to work out the average rating given by Amazon users to various products - the data is real! The data is presented as a frequency table. Solutions are provided.
A good resource to use in a poster-making lesson!
