1 JC1 H2 Geography End-of-Year Examination Suggested Answers Section A 1. A group of 10 students carried out an investigation to look into the needs of the elderly living in urban neighbourhoods, particularly the homeless in Singapore. They decided on the following hypothesis for their investigation: ‘Homelessness is more pre valent amongst the lower income elderly in Singapore because they cannot afford to pay for housing.’ The group decided to do a survey on the homeless elderly around Singapore via a questionnaire that is being translated to the 3 major languages – Mandarin, Malay and Tamil. They have decided to do their survey in different parts of Singapore where they stay. They also plan to do their survey from 10pm to about 12midnight on a Friday, and look for them at void decks and near closed eateries. Resource 1 shows an infographic of the homeless in Singapore. Resources 2A and 2B show the questionnaire survey (the English version) the students used in their investigation and the selected results of the questionnaire survey. Resource 3 shows how the Singapore government is helping the elderly population in terms of housing. (a) Explain whether the student’s hypothesis is capable of research. [4] Award 1 mark for each explanation of why the hypothesis is capable of research, to a maximum of 4m. Award a maximum of 1 additional mark for further development of each explanation, where applicable. Possible responses include: Yes, capable of research.  Clearly defined – identified a specific target group: lower income elderly [1m] There are limitations to the research.  Not a suitable scale – whole of Singapore too big a scale for 10 students, and doing GI on only one Friday night is too short a time with too little manpower to yield many samples ( Resource 2B shows only 24 samples – too small a sample for a hypothesis that investigates on Singapore). [1m]  Not fully researchable – Although the students might be able to find some homeless elderly in the neighbourhood that they live in and are familiar with, and be able to ask some questions through the questionnaire, [1m] they have not familiarise themselves with secondary data available - like where the homeless are congregated (eg. Downtown, Bedok, Kallang), and research those more populated areas instead. [1 additional mark]

2 (b) With reference to Resources 1 and 2A, explain how the students can best collect data on the homeless elderly in Singapore. [4] Award 1 mark for each explanation of how students can best collect data on the homeless elderly in Singapore. Award a maximum of 1 additional mark for further development of each explanation, where applicable. Possible responses include:  Resource 1: To determine a sample size and to have enough manpower for collecting data for the area (ie . Singapore) [1m]. If they are limited to 10 students, they should then do a stratifie
