Prelim 4E GY 2279/01 2025 2 1 Cluster 1: Geography in Everyday Life A group of students from Horizon High School is interested to find out residents’ perception of urban heat within a precinct. They want to investigate if the type of surface material influences the likelihood and frequency of residents spending time in various outdoor locations. They tested the hypothesis: ‘Residents prefer to visit outdoor locations with natural surfaces than artificial ones due to lower perceived heat.’ To prepare for their investigation, the students conducted a pilot survey on a Saturday afternoon. Fig. 1.1 shows an excerpt from their fieldwork journal that documents insights gained during the pilot survey. Excerpt from the students’ fieldwork journal on the pilot survey Date: 5 May 2025 Time: 2:00 PM - 4:00 PM Location: Ang Mo Kio Block 400s (near a small community garden) Sample size: 10 residents Notes: - Managed to find respondents quite easily. Many residents were reluctant to stop for long interviews due to the heat. Administered a short closed -ended questionnaire and attempted mental mapping. Some participants found it hard to draw detailed maps from scratch. Q5 was interpreted differently by different respondents. Fig. 1.1 (a) (i) Suggest a measure that students could implement to mitigate a possible risk they may face during their investigation. ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ....................................................................................................................

(i) Explain why convenience sampling may not be an appropriate choice of sampling method for their investigation. ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ....................................................................................................................

Prelim 4E GY 2279/01 2025 4 (ii) Study Table 1.1 (Insert), which shows information the students collected with the questionnaire. Using Table 1.1, describe the relationship between the residents’ likelihood and frequency of visits to the different locations. ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ......................................................................................................................... ....................................................................................................................
