Data handling question bank

Questions on collecting and organising data, tally marks and frequency tables, pictographs, bar graphs and pie charts, and the four summaries: mean, median, mode and range. They grow from foundation (one step) through core and stretch to challenge (olympiad-style reasoning). Every question has a worked solution; try it yourself before opening it. Tip for many averages problems: switch from the mean to the total, because sum = mean × count.
