About this lab: Averages and charts

Interactive simulation for Cambridge IGCSE Mathematics 0580 topics 9.1 to 9.4: drag values on a dot plot to see the mean balance, the median and mode move and the range change, with quartiles and interquartile range, work from ungrouped and grouped frequency tables with tallies to the mean and estimated mean, draw bar, pie, dual and composite bar charts and pictograms from the same data, build ordered stem-and-leaf diagrams with a key, and compare two classes using an average and a measure of spread.

IGCSE Mathematics 0580, topics 9.1 to 9.4. Mean, median, mode and range, frequency tables, bar charts, pie charts, pictograms, stem-and-leaf diagrams and comparing two data sets.

Averages and charts is a free, browser-based simulation for Cambridge IGCSE Mathematics 0580 (topic 9 Statistics, sections 9.1 Classifying statistical data, 9.2 Interpreting statistical data, 9.3 Averages and measures of spread and more). The course is assessed in Paper 1 (Core non-calculator), Paper 2 (Extended non-calculator), Paper 3 (Core calculator), Paper 4 (Extended calculator). Syllabus for examination in 2025-2027. There are 5 tabs, each a self-contained experiment with its own controls and live readings, and nothing to install: it runs on a laptop, tablet or classroom projector.

How to use this simulation

1. Averages and range.
2. Frequency tables.
3. Charts.
4. Stem-and-leaf.
5. Comparing data.
The buttons at the end of the tab strip give the scene the whole window (Full screen, Hide controls) and, on a dark stage, a projector-friendly palette (Light scene). Many scenes also have drag handles: drag them to change the set-up directly.
