What is GCSE Statistics?
Statistics is about making sense of data. You'll learn to calculate averages, draw and interpret graphs, and compare data sets. These skills are essential in science, business, and everyday decision-making.
- Averages & spread – mean, median, mode, range, quartiles
- Data representation – bar charts, pie charts, scatter graphs
- Cumulative frequency – diagrams, medians, quartiles, box plots
- Histograms – frequency density and grouped continuous data
