Statistics
Daily-habit recall for GCSE Statistics, the fastest-growing GCSE in England. Named techniques, precise definitions, and the calculations that come up on every paper. Built for the data-handling content that general Maths revision tools fold in and rush past.

~35k
GCSE entries / year
The fastest-growing GCSE in England, up roughly 9% in 2025 and around 96% since 2021. Usually sat alongside GCSE Maths, often in Year 10, as a discrete data-handling qualification that universities and employers value.

Boards in scope
Edexcel (1ST0) is the dominant spec and the primary authoring target; AQA (8382) shares the bulk of the content: sampling, averages, diagrams, probability and index numbers. Per-card boards tagging handles the board-specific detail.

Fit for spaced repetition
Statistics is precise definitions plus clean, repeatable calculations: stratified vs systematic sampling, discrete vs continuous data, the mean from a frequency table, the interquartile range, index numbers. Our calculation card type, built for Business, transfers across directly.
What's covered
Definitions, diagrams and clean calculations, spec-anchored.
GCSE Statistics rewards students who can name the right technique and execute the calculation under time pressure. Educator's recall mechanic turns 'something about sampling' into 'stratified (proportional by subgroup) every time'.
Collecting data
- ✓Sampling: random, systematic, stratified, quota, cluster
- ✓Populations, sampling frames and sampling bias
- ✓Primary vs secondary; qualitative vs quantitative data
- ✓Discrete vs continuous data; census vs sample
- ✓Questionnaire design and sources of bias
Processing & summarising
- ✓Mean, median, mode and the modal class
- ✓Range, quartiles and the interquartile range
- ✓Standard deviation and measures of spread
- ✓Mean from a frequency / grouped frequency table
- ✓Weighted means and estimating from grouped data
Representing data
- ✓Histograms, unequal class widths and frequency density
- ✓Cumulative frequency curves; median and quartiles
- ✓Box plots and comparing distributions
- ✓Scatter graphs, correlation and the line of best fit
- ✓Time series and moving averages
Probability & distributions
- ✓Theoretical vs experimental probability
- ✓Tree diagrams and Venn diagrams
- ✓Expected frequency and assessing risk
- ✓The normal distribution and standard deviation
- ✓Spearman's rank correlation coefficient
Index numbers & quality
- ✓Simple and weighted index numbers
- ✓RPI, CPI and the cost of living
- ✓Chain base index numbers
- ✓Quality assurance and control charts
- ✓The data-handling cycle, end to end
Spec-faithful, authoring in progress. Cards will cover: the data-handling cycle; collecting data (random, systematic, stratified, quota and cluster sampling; primary vs secondary; questionnaire design and bias); processing data (mean, median, mode, range, quartiles and the interquartile range, standard deviation, weighted means); representing data (histograms with unequal intervals, cumulative frequency, box plots, stem-and-leaf, scatter graphs, time series and moving averages); index numbers (RPI, CPI, chain base); probability (tree and Venn diagrams, expected frequency); correlation and regression (line of best fit, Spearman's rank); and quality assurance (control charts and the normal distribution).
