GCSE Statistics Revision

GCSE Statistics is a separate GCSE from GCSE Maths, with its own content and its own exam papers. This app is built for that qualification: practice questions, revision notes and a mock test for students taking GCSE (9–1) Statistics with Edexcel (1ST0) or AQA (8382).

It suits students in Year 10 or Year 11, including those taking it early alongside GCSE Maths, and parents or teachers who want a structured way to revise.

WHAT'S INSIDE
• 1,317 exam-style questions across 88 subtopics on the Edexcel course, and 1,249 across 86 subtopics on the AQA course
• A revision note for every subtopic, with key facts, the method, a diagram and a worked example with a step-by-step solution
• A full explanation with every question, so you see why the right answer is right and why the others are wrong
• Hundreds of charts and diagrams drawn to scale from exact data, so you read real values off the graph
• A Mock Test that draws questions from every topic

FIVE STRANDS, ONE TILE EACH
• Collecting data: planning an investigation, types of data, sampling methods, questionnaires, bias, and controlling variables
• Representing data: tables, bar and pie charts, stem and leaf, population pyramids, choropleth maps, frequency polygons, cumulative frequency, box plots, histograms, misleading diagrams and skew
• Summarising data: averages, quartiles and percentiles, outliers, comparing distributions, standard deviation, standardised scores, index numbers, and birth and death rates
• Analysing data: scatter diagrams, correlation and causation, lines of best fit, regression, Spearman's rank, time series, moving averages, seasonal variation, estimation and control charts
• Probability: Venn and tree diagrams, two-way tables, independent and conditional probability, relative risk, and the binomial and normal distributions

FOUNDATION AND HIGHER
When you first open the app, choose your exam board and tier. Foundation hides the Higher-only subtopics and keeps them out of the Mock Test. Higher shows everything. Not sure yet? Choose that, and you can change it later in Settings without losing your progress.

INTERPRETING AND EVALUATING
Exam papers ask you to compare, interpret and judge, not just calculate. Many questions ask which statement is the best comparison, which feature makes a chart misleading, or which conclusion the data supports. The explanation then gives
