This is a video to accompany my article for the TES Magazine ('Dotty Thinking') that offers up a simple, fun idea to get students engaged and making meaningful data comparisons, including mean, median, mode, range and a whole host of statistical diagrams including cumulative frequency, histograms and bar charts. Click the links below to see the article and download the resources (Video tutorial, PowerPoint and Excel). Ideal for KS3 and GCSE students.

    The best resource I have ever used to bring Averages to life. Students loved it, talked about it and more importantly understood the averages. Thanks for sharing.

    Thank you for this. To adapt for KS2, you can set the task up as 'which team are the best guessers'? Children then have a smaller data set to work with when calculating the mean.
