Here is a task I made for my class studying GCSE statistics group but also used with my higher group. Pupils are required to complete a number of tasks to decide who should replace santa; buddy the elf or Fred Claus. Requires pupils to construct a table of data, cumulative frequency diagram, read information from it, then construct a box blot (box and whisker) and interpret the results. I prints the pages from the IWB and used them as worksheets! Enjoy Christmas Maths!
