4 9751/02/IJC/SEP17 Section A Theme 3: Geographical Investigation 1 A group of 20 18 year old students from a junior college in Singapore wanted to examine the impact of industries on local communities. They have decided to study the impact of Nordcom 1 and Nordcom 2, which are two new light industrial areas located near a residential area in Woodlands. The students wanted to gather information on the impact of the industrial area on the residents living nearby, especially in terms of noise, po llution and economic impact. They were given one week to complete their investigation in August in 2018. The students then decided to divide themselves into four teams of 5. Two teams carried out their investigation in the newly completed residential areas, HDB Sun Natura and HDB Sun Breeze; and two other teams carried out their investigation in the residential areas further away. They have decided to carry out questionnaire surveys by approaching residents who were walking by the shops or at food establishments. The questions asked in the survey were: • “To what extent has the setting up of Nordcom 1 and 2 made an impact to your life?” • “Has the impact been largely positive or negative?” • “Has the presence of Nordcom 1 and 2 brought more income to the area?” • “Are you affected by the noise or pollution generated from Nordcom 1 or 2?” The investigation was conducted from 12pm to 1pm each day. Each group interviewed 25 residents in total. Resource 1 shows a map of the surrounding area of Nordcom 1 and 2. Resource 2 shows the profile of Nordcom 1 and 2, explaining the type of activities found in the area. Resource 3 shows the collated results from the questionnaire survey. (a) With reference to Resources 1 and 2, suggest a suitable hypothesis for the investigation and explain two reasons why the research is at a suitable scale. [3] • The residents living nearest to Nordcom 1 and Nordcom 2, in Sun Natura and Sun Breeze, will face greater impact from the industrial areas compared to the residents living in residential areas further away. [1] • Any two: o Enough manpower to conduct investigation. 20 students broken into four teams of 5. o Given time of one week is sufficient and manageable. o Area given is manageable, with the furthest residential area about 400m away from Nordcom 1 and 2.

5 9751/02/IJC/SEP17 (b) With reference to Resource 1 and the context provided, suggest and describe a suitable sampling method for the investigation. [3] From notes: o simple random sampling : giving each member of the population an equal chance of being selected for the investigation (e.g. rolling a dice and selecting from a list of possible questionnaire respondents) o systematic random sampling: selecting every kth element of the sampling frame, beginning with a randomly chosen point (e.g. selecting the 9th person from an ordered list of respondents to interview) o stratified random sampling: selecting a simple random sample from given subgroups in the population (e.g. randomly select 5 focus group participants from different age cohorts) (c) Your group concluded that the method of data collection through the questionnaire survey may not be completely reliable and accurate. Explain how the process of data collection could be improved. [7] Possible points (must be linked to accuracy/reliability) • HDB Sun Natura and HDB Sun Breeze are newly completed (Sun Natura in mid 2018) and the residents may not have lived in the area long enough to truly gauge the impact of Nordcom 1 and 2, as shown in responses to Q3 as well  questionnaire survey could take note of how long they have lived in the area • Similarly, Nordcom 2 is only ready in Dec 2018, which means that the residents may not be able to truly appreciate the impact of having Nordcom 2 in the area, especially in terms of positive impact  could have chosen a different location with a more established industrial area • Questions too vague - may not truly reflect the impact felt to residents in the area  could have probed to asked for examples on how the area has left an impact • 12pm – 1pm on weekdays would mean that the results would mostly come from elderly residents who are unemployed, or adults who are not working, such as housewives. Therefore, may not be able to get representative data.  could have conducted it on weekends or at different times of the day. • Sample size might be too small to get a representative conclusion (as also seen in Resource 3)  the team could have increased the sample size

6 9751/02/IJC/SEP17 Level Marks Descriptors 3 6-7 Response demonstrates accurate knowledge of survey collection methods, issues with both accuracy and/or reliability of these and relevant improvements. Reflects a good understanding of the context of the investigation and of data collection techniques. 2 3-5 Response demonstrates good knowledge of survey collection methods. Provides an explanation of issues relating to reliability and/or accuracy with some reference to possible improvements. Some of the responses may focus on generic fieldwork issues and improvements may not be relevant to the context of the investigation. 1 1-2 Response shows some knowledge of survey collection methods. Some reference is made to issues with reliability and/or accuracy but may recommend irrelevant or inappropriate improvements or provide inaccurate explanation of methods. Response may be of limited relevance to the given context. 0 0 No creditworthy response. (d) Suggest one limitation of the data representation method shown in Resource 3 and sketch an alternative data representation method to show the perception of the residents on the extent to which the setting up of Nordcom 1 and 2 have made an impact to their lives. • Table – difficult to compare visually • Any suggested data representation met hod that would allow for easy visual comparison. Must include: o 1m title o 1m accuracy of data o 1m labelling [4] (e) Evaluate the usefulness of the data shown in all the resources in helping students understand the impact of industries on local communities. Possible points for usefulness (all these need elaboration): • R1 – useful to show the distance between residential areas and industrial areas. • R2 – useful to understand the activities that goes on in Nordcom 1 and 2 and potential impa
