The 20 questions

  1. In fieldwork, what term describes the entire set of things you could potentially measure?

    • Population
    • Interval
    • Transect
    • Sample

  2. What is the smaller subset of points actually measured to represent a whole study area?

    • Hypothesis
    • Sample
    • Average
    • Population

  3. Why do geographers usually collect a sample instead of measuring an entire population?

    • Increases area
    • Stops errors
    • Removes bias
    • Saves time

  4. What error occurs when a sample over-represents one specific type of place or person?

    • Random error
    • Bias
    • Systematic flaw
    • Anomalous data

  5. Which sampling strategy uses a fixed, regular interval such as every 50 metres?

    • Systematic sampling
    • Biased sampling
    • Random sampling
    • Stratified sampling

  6. Which sampling strategy splits the study area into groups before sampling each group?

    • Quadrat sampling
    • Stratified sampling
    • Systematic sampling
    • Random sampling

  7. What is the interval for 4 systematic readings along a 200 metre transect?

    • 40 metres
    • 20 metres
    • 50 metres
    • 100 metres

  8. Surveying only the busiest street in a town creates which major fieldwork problem?

    • High accuracy
    • Random error
    • Large sample
    • Sample bias

  9. Why is a representative sample essential before drawing a geographical conclusion?

    • Speeds up fieldwork
    • Prevents misleading results
    • Removes all walking
    • Increases sample size

  10. Which sampling strategy uses a fixed interval along a straight path to remove personal choice?

    • Random
    • Stratified
    • Opportunistic
    • Systematic

  11. Which sampling method gives every single location an equal mathematical chance of selection?

    • Stratified
    • Systematic
    • Random
    • Pilot

  12. A student surveys 8 streets chosen fairly out of 40 total streets. What is the population?

    • The 8 streets
    • All nearby towns
    • Just 1 street
    • All 40 streets

  13. Which sampling strategy ensures the most even spatial coverage along a linear footpath?

    • Random
    • Biased
    • Systematic
    • Opportunistic

  14. What is a major risk of using systematic sampling along a fixed interval line?

    • Clustering points
    • High personal bias
    • Too much time
    • Missing hotspots

  15. What is a major risk when using random sampling across a large field site?

    • Clustering points
    • Fixed intervals
    • No randomness
    • Zero chance

  16. Which sampling method divides a town into distinct sub-groups like rich and poor areas?

    • Systematic
    • Stratified
    • Random
    • Opportunistic

  17. Choosing parks just because they are easy to reach introduces what main fieldwork issue?

    • Sample bias
    • Systematic interval
    • Equal chance
    • Large population

  18. Why can a larger fieldwork sample still be untrustworthy?

    • It is too expensive
    • It takes too long
    • It lacks numbers
    • It remains biased

  19. What must a fieldwork sample be to apply to the whole area?

    • Systematic
    • Random
    • Qualitative
    • Representative

  20. Why do geographers use systematic sampling along a footpath?

    • Even spacing
    • Random selection
    • Quickest time
    • Cheapest cost
