What is Types of Data & Sampling?
Types of Data & Sampling belongs to Statistics in GCSE Mathematics. The reliable way to revise it is to learn the trigger condition, write the first method line clearly, and practise enough variations that you can spot when the standard method needs adapting. For GCSE Maths, protect method marks by showing each transformation rather than jumping to the final answer.
Board notes: AQA, Edexcel and OCR differ in wording and calculator/non-calculator balance. Use this as a method lesson, then check your board specification and past-paper style for exact demand.
Step-by-step explanationWorked examples
Worked example
For a Types of Data & Sampling question, first classify the problem: what information is given, what form should the answer take, and which rule from Statistics applies? Write the method line, carry out each transformation cleanly, then substitute or check the result against the original condition. This creates a mark-scheme-friendly answer even when the arithmetic is demanding.
Practise this topic
Start with low-focus cards for Types of Data & Sampling, then move into full exam-style practice when you want the heavier session.
Targeted practice plan
- 1Do one Types of Data & Sampling question where the method is obvious, then rewrite the first line so it would earn a method mark.
- 2Do one mixed Statistics question and identify the exact trigger that tells you it is testing Types of Data & Sampling.
- 3Redo the same question without notes and check final form, units, rounding and whether every algebra line follows.
Common mistakes
- 1Starting calculations before identifying the exact form of the question.
- 2Skipping algebraic or numerical working that the mark scheme would credit.
- 3Not checking whether the final answer needs units, exact form, a diagram interpretation, or a stated conclusion.

Frequently asked questions
How do I get better at Types of Data & Sampling?
Practise in short sets: one easy recognition question, one standard method question, and one mixed question. After each attempt, mark the first line and the final check separately.
What loses marks in Types of Data & Sampling?
Most lost marks come from wrong method selection, missing intermediate steps, or an answer that is mathematically correct but not in the requested form.
