Secondary 3 Geography Quiz - Fieldwork: Answer Key
Total Marks: 40
Level: Secondary 3 | Topic: Fieldwork (syllabus-first practice, not exam-derived)
Section A: Answers (1 mark each)
-
To collect primary data and observe geographical phenomena in the real world.
Teaching note: Fieldwork connects classroom learning to actual places; it helps students test hypotheses. -
Survey responses / photographs / measured temperatures / observation notes. (any one)
Teaching note: Primary data are gathered first-hand by the student during the study. -
Interview / mental map / photograph with notes. (any one)
Teaching note: Qualitative data describe qualities and perceptions, not just numbers. -
A testable statement predicting a relationship between variables.
Teaching note: E.g., "Pedestrian count is higher near train stations." -
Random sampling.
Teaching note: Each person or site has equal chance; reduces bias. -
Median.
Teaching note: Order data, the middle value is median; mean is average, mode is most frequent. -
Mental map.
Teaching note: Mental maps show personal spatial perception, not exact scale. -
Wear bright clothing / stay on pavement / work in pairs. (any one)
Teaching note: Safety is part of fieldwork planning. -
To test methods / find errors before real data collection.
Teaching note: Pilot study improves reliability. -
Dividing population into groups then sampling from each group.
Teaching note: Strata are based on traits like housing type; improves representation.
Section B: Answers (2 marks each)
-
Convenience sampling selects whoever is easy to reach (1). Quota sampling sets amounts per group to match population (1).
Teaching note: Convenience is fast but biased; quota improves representativeness. -
Any two: bar chart, line graph, table, pie chart (1 each).
Teaching note: Visuals help compare counts across locations. -
Ask residents to rate attachment / list favourite places (1); use answers to map sense of place (1).
Teaching note: Questionnaires can capture emotional and social links to place. -
Any two: informed consent, anonymity, no harm, respect privacy (1 each).
Teaching note: Ethical fieldwork protects participants. -
Lay transect across both estates (1); count trees at intervals to compare (1).
Teaching note: Transect shows spatial pattern; data test hypothesis. -
Gives past context / saves time / compares with own readings (1); e.g., confirms heat trend (1).
Teaching note: Secondary data support primary findings.
Section C: Answers (3 marks each)
-
Mean = (120+85+140+40) ÷ 4 = 385 ÷ 4 = 96.25 (2 marks: 1 for sum, 1 for division). Busiest: 17:00–18:00 (140) (1 mark).
Teaching note: Mean is average; highest bar shows peak use. -
Difference at 12:00 = 34 − 30 = 4°C (2 marks: identify 34 and 30, 1; subtract, 1). Reason: car park has less vegetation and more heat-absorbing surfaces (1).
Teaching note: Graph shows urban heat; surfaces like asphalt raise temperature. -
Primary issue: small sample (50) may not represent all visitors (1). Secondary issue: no comparison site or time pattern for litter (1); account lacks method detail (1).
Teaching note: Good fieldwork needs clear sampling and controls. -
Map shows school is central to her daily life and mall is strongly linked (1). Limitation: mental maps are subjective, not to scale (1); may miss less familiar areas (1).
Teaching note: Sense of place is personal; maps vary by experience.
