Students who lived in Southern Thailand were interested in the effects of tourism in their local town, Hua Hin. They decided to investigate the environmental and economic effects of tourism in different areas of the town. They agreed on the following hypotheses: Hypothesis 1: Tourism has a negative impact on the environment of Hua Hin. Hypothesis 2: Tourism has an economic benefit for the residents of Hua Hin.

1. (a)(i)To carry out their fieldwork the students identified ten survey sites in the town. These are shown on Fig. 13 (Insert). At each site the students wanted to estimate the importance of tourism. They based their decision on whether shops in the area were used mainly by local people or tourists. Suggest three ways that they could decide whether shops were used mainly by local people or tourists.[3]
2. (a)(ii)Before starting their fieldwork the students did a small pilot (trial) survey near their school. Give two advantages of doing a pilot survey.[2]
3. (a)(iii)The results of the students' fieldwork are shown in Table 4, below. Use these results to complete the divided bar for site 5 on Fig. 14 below.[2]
4. (a)(iv)The students then decided to rank the ten sites in order of importance for tourism. To do this they first calculated the percentage of shops used mainly by tourists at each site using the following formula: number of shops used mainly by tourists × 100 / total number of shops. The number of shops at the pilot survey site is shown in Table 4. In the space below calculate the percentage of shops at this site used mainly by tourists. Show your calculation.[2]
5. (a)(v)The results of this calculation for the ten actual survey sites are shown in Table 5 below. Complete the rank order of the percentage of shops used mainly by tourists by inserting ranks 1 to 5.[1]
6. (b)(i)Having decided how important tourism was at the ten sites, the students then did an environmental quality survey at each site. The scoring chart which they used for the pilot survey is shown in Fig. 15 below. The students' decisions are circled. Calculate the total environmental score for the pilot survey site and insert your answer in the box below Fig. 15.[1]
7. (b)(ii)Give two possible weaknesses of an environmental quality survey.[2]
8. (b)(iii)The two sets of results for percentage of shops used mainly by tourists and environmental score at the ten sites are shown in Table 6 (Insert). Plot the results for sites 4 and 7 on the scatter graph, Fig. 16, below.[2]
9. (b)(iv)Draw a best-fit line on Fig. 16.[1]
10. (b)(v)The students rejected Hypothesis 1: Tourism has a negative impact on the environment of Hua Hin. Give one piece of evidence from Fig. 16 to explain why they rejected the hypothesis.[1]
11. (b)(vi)Suggest two reasons for the relationship shown in Fig. 16.[2]
12. (c)(i)To get data for Hypothesis 2: Tourism has an economic benefit for the residents of Hua Hin the students used a questionnaire. At each site they questioned 20 people. The questionnaire which they used is shown in Fig. 17 (Insert). How would the students use a systematic sampling technique with their questionnaire?[1]
13. (c)(ii)The results of Question 2 obtained from 20 residents at site 3 are shown below. Q2 Overall do you think tourism has an economic benefit in Hua Hin? Yes 11 No 9 Plot these results on Fig. 18 below.[1]
14. (c)(iii)The results of Question 3 obtained from 20 residents at site 3 are shown below. Q3 What do you think is the main benefit of tourism in Hua Hin? More job opportunities 6 Improved standard of living 5 Improved infrastructure 3 Greater range of goods in shops 3 More modern services 3 Plot these results onto the tally chart, Fig. 19 below.[2]
15. (c)(iv)What conclusion can you make about Hypothesis 2: Tourism has an economic benefit for the residents of Hua Hin? Support your answer with evidence from Figs 18 and 19.[4]
16. (d)Local people identified more job opportunities and an improved standard of living as the main benefits of tourism. Why are these the main benefits of tourism?[3]
