Senior Secondary (HKDSE) · Geography
5 multiple-choice questions marked as you go, and 5 written questions with worked solutions. All on Fieldwork methods & questionnaires.
Original chapter practice: 50 marks. Suggested time: 75 minutes (Thinka practice estimate, not an official exam duration). Answer all 10 questions. All sites and numerical datasets are synthetic teaching examples. This is not a full official HKDSE paper. Use a calculator, ruler and pencil; show units and working.
For the 2027 HKDSE, which pair is the prescribed fieldwork module pool?
Starting at a randomly chosen point, a student samples sediment every 5 m along a transect. This is:
Which questionnaire item is most neutral and asks one thing?
A thermometer repeatedly reads 2°C above a calibrated reference. More repeated readings alone will:
How is fieldwork assessed in the relevant HKDSE framework?
A synthetic promenade population is 60% residents and 40% visitors. You plan 50 interviews. (a) Allocate a proportional stratified sample. [2] (b) Describe selection within the groups and timing that reduce bias. [2] (c) State one consent or privacy practice. [1]

Students ask: “Don’t you agree the new park is clean and safe?” (a) Identify two distinct design faults. [2] (b) Replace it with two neutral questions and a suitable response scale. [3]

A beach team chooses only large visible pebbles near the entrance. An urban team rates litter from 1 to 5 without defining the scores. (a) Explain the bias in the beach method and a targeted improvement. [2] (b) Explain the urban comparability problem and two targeted improvements. [3]

Coastal enquiry — all sites and data are synthetic. Question: “Is coarser surface sediment associated with a steeper beach?” At three transects measured at similar tide stage, median pebble intermediate-axis diameters are A 12 mm, B 24 mm, C 36 mm; vertical rises over 20 m horizontal distance are A 1 m, B 2 m, C 4 m. All sediment samples contain 20 pebbles. Figure C locates the transects. (a) State a testable directional hypothesis and one control. [2] (b) Describe how to measure a comparable profile and collect an unbiased pebble sample, including one safety action. [4] (c) Calculate the three percentage gradients and choose a graph to test the relationship. [3] (d) Draw a conclusion with data and a plausible process. [3] (e) Explain one limitation, its effect and a targeted improvement. [3]

Sustainable-city enquiry — synthetic data. Investigate whether shaded streets are cooler and more comfortable. At noon on one day, S1/S2/S3 (shaded) record 29/30/31°C; U1/U2/U3 (unshaded) record 32/33/34°C. At each group of streets, 15 of 20 shaded-street respondents and 8 of 20 unshaded-street respondents report feeling comfortable. Respondents were selected by convenience. (a) State a testable hypothesis and a geographical reason. [2] (b) Propose comparable temperature measurements and a better questionnaire sampling design, including ethics. [4] (c) Calculate both mean temperatures and both comfortable-response percentages. [3] (d) Give an evidence-based conclusion and one cautious management suggestion. [3] (e) Explain a limitation, its effect and a matched improvement. [3]
