Question 1 · 1 mark · Difficulty 1/3

A researcher wants to select 10 students from a class of 30. She numbers each student 1–30 and uses a random number generator to pick 10 different numbers. Which sampling method is this?

  1. A: Stratified sampling
  2. B: Systematic sampling
  3. C: Simple random sampling
  4. D: Opportunity sampling
Show answer & explanation
✓ Answer: CC: Simple random sampling
Simple random sampling gives every member of the population an equal chance of being selected, and using a random number generator to pick from a numbered list achieves this. Stratified sampling divides the population into groups first, and systematic sampling uses a fixed interval rather than random numbers.
Question 2 · 1 mark · Difficulty 2/3

A school has 400 students: 160 in Key Stage 3 and 240 in Key Stage 4. A stratified sample of 50 students is needed. How many should be selected from Key Stage 4?

  1. A: 20
  2. B: 25
  3. C: 30
  4. D: 40
Show answer & explanation
✓ Answer: CC: 30
Key Stage 4 makes up 240/400 = 0.6 of the population, so the sample should contain 0.6 × 50 = 30 students. A common error is to split the sample equally (25 each) rather than proportionally. Another error is using the wrong group (Key Stage 3 gives 20 students).

AQA GCSE Mathematics: Sampling methods and questionnaire design FAQ

How many AQA GCSE Mathematics questions on Sampling methods and questionnaire design are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Sampling methods and questionnaire design for AQA GCSE Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Sampling methods and questionnaire design practice with other Mathematics topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Sampling methods and questionnaire design questions aligned to the official AQA GCSE Mathematics syllabus?
Every question is written against the published AQA GCSE Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Sampling methods and questionnaire design typically tested on AQA GCSE Mathematics papers?
Sampling methods and questionnaire design appears across multiple question types on real AQA GCSE Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
