Four Fours:Choosing the best average
Sixteen situations, lists and small charts sorted by what should describe them: the mode, the median, the mean or the range. Two dot plots differ by one value, and that outlier changes the answer from the mean to the median. Two per A4.
A free key stage 3 and GCSE statistics puzzle with answers, spec code S5. It goes with the lesson on choosing the best average.
