This is a look at the grouped data and in particular the estimated mean. This still tends to be a popular exam question at GCSE and a question year on year done poorly. This whole lesson has some excellent teaching slides, which will promote understanding as well as a useful worksheet to use.
It comes with the usual starter, learning objectives, keywords, excellent teaching slides, worksheet with answers and plenary. All averages lessons are available in my shop as well as in a bundle at a slightly reduced cost.
