The 20 questions

  1. What is a key strength of random sampling?

    • No population list
    • Quick execution
    • High representativeness
    • Very low cost

  2. What is a main weakness of random sampling?

    • High researcher bias
    • Time-consuming
    • Unrepresentative by design
    • Cannot be replicated

  3. What is a major strength of opportunity sampling?

    • Highly representative
    • Uses complete lists
    • Quick and easy
    • Free from bias

  4. What is a main weakness of using opportunity sampling in research?

    • High cost
    • Unrepresentative sample
    • Complex setup
    • Time consuming

  5. What is a major strength of using systematic sampling?

    • Guarantees proportion
    • Avoids researcher bias
    • Always representative
    • Fastest method

  6. What is a potential weakness of using systematic sampling?

    • Informed consent
    • High researcher bias
    • Hidden list patterns
    • Time consuming

  7. What is the primary strength of using stratified sampling?

    • Highly representative
    • Requires no data
    • Quick to gather
    • Zero bias

  8. What is a main weakness of using stratified sampling?

    • Small sample size
    • Time consuming
    • Researcher bias
    • Unrepresentative sample

  9. Why might findings from an opportunity sample lack population validity?

    • High cost
    • Sample bias
    • Ethical issues
    • Measurement error

  10. Which sampling technique is the quickest and cheapest to conduct?

    • Random sampling
    • Opportunity sampling
    • Stratified sampling
    • Systematic sampling

  11. Which sampling technique ensures target population subgroups are represented proportionally?

    • Systematic sampling
    • Random sampling
    • Opportunity sampling
    • Stratified sampling

  12. What is the main drawback of having a very small sample size?

    • Unrepresentative sample
    • Greater cost
    • Ethical issues
    • High bias

  13. What is an advantage of systematic sampling from a target population list?

    • Guarantees proportion
    • Avoids researcher bias
    • Fastest method
    • Eliminates dropouts

  14. What is a potential drawback of random sampling with small sample sizes?

    • Accidental bias
    • Lack of consent
    • High researcher bias
    • Time limit

  15. Compared to opportunity sampling, what benefit does random sampling offer?

    • Easier setup
    • More representative
    • Quicker process
    • Lower cost

  16. Which sampling method ensures every school year group is proportionally represented?

    • Opportunity sampling
    • Stratified sampling
    • Systematic sampling
    • Random sampling

  17. Why might sampling people at a leisure centre introduce sample bias?

    • Ethical conflict
    • High cost
    • Time delay
    • Unrepresentative participants

  18. When might systematic sampling accidentally produce a biased sample?

    • List has patterns
    • Large sample size
    • Equal intervals
    • Random start

  19. What is a major disadvantage of stratified sampling compared to opportunity sampling?

    • Less representative
    • Higher demand characteristics
    • Increased order effects
    • More time-consuming

  20. What is the main advantage of using stratified sampling in research?

    • Quickest to conduct
    • Easiest to organise
    • Eliminates researcher bias
    • Highly representative
