What is it
GCSE Foundation statistics covers collecting, representing and interpreting data using bar charts, pie charts, and frequency tables, plus calculating averages (mean, median, mode) and range.
Why it matters
Statistics questions are often 'easy marks' if the underlying arithmetic is solid — the concepts themselves are usually more accessible than algebra or geometry, making this a high-value topic to be fully confident in.
Exam tip
When constructing a pie chart, always calculate the angle for each category as (frequency ÷ total) × 360° — forgetting to multiply by 360 is a very common and entirely avoidable error.
