A short Powerpoint to explain how to find an estimate of the mean from a grouped frequency table. Also with this resource, there is a pdf worksheet (with complete answers). The worksheet has one A4 side containing 3 questions, and the PDF also contains a completed version with the answers shown in red.
This powerpoint has been revised and now has 8 slides (previously 4) (Including one title and one end slide). There are six examples similar to the one shown in the illustration. Designed for KS4 / GCSE.
You have access to the original powerpoint plus the revised one.
