Raise and lower data bars and watch the mean, median and range shift live. Balance the mean onto a target line, centre the median, and set the range — statistics you can see.
Each challenge presents a set of data bars that a child adjusts up or down, watching the mean, median, and range respond in real time — then tweaking until one statistic lands on a target value. The live feedback makes the relationship between data and summary statistics tangible rather than formula-driven. A strong fit for Grades 4–6, or anyone who finds statistics abstract without a visual anchor.
A free, no-signup, no-ads math game for Grades 4–6 — practising mean, median, range, data. Play in your browser on the KidsDoMath games hub or explore more Data & Probability games.
