GCSE Maths: Relative Frequency
Calculate relative frequency and use it to estimate probability. Practise it with adaptive questions for AQA, Edexcel, OCR and Eduqas.
What you need to know
The concepts examiners test on relative frequency, and what each one is really asking.
Where marks get lost
The exam technique that separates a correct method from a correct answer.
- Thinking relative frequency is always exactly equal to theoretical probability (it's only an estimate!)
- Adding instead of multiplying when estimating future outcomes
- Forgetting that probabilities must add up to 1
Relative Frequency questions students ask
Is Relative Frequency on the Foundation paper?
Yes. Relative Frequency appears at both Foundation and Higher tier, though Higher papers take it further.
What should I know before starting Relative Frequency?
It builds on Basic probability. If those feel shaky, practise them first — Relative Frequency questions assume them.
What is the most common mistake in Relative Frequency?
Thinking relative frequency is always exactly equal to theoretical probability (it's only an estimate!).
Which exam boards cover Relative Frequency?
All four we support — AQA, Edexcel, OCR and Eduqas. GCSE Maths subject content is set by the DfE, so the topic is common to every board; what changes is the paper structure and the grade boundaries.
