State whether the hypothesis has been proven or disproven. Support your stand using evidence in Fig. 6. ·        The hypothesis has been proven. ·        The bipolar graph has most of the responses at a positive numbers. [1] ·        For example, response for well-kept buildings has about 43 positive responses. [1] ·        For example, response for the litter around has about 42 positive responses. [1] BEATTY SEC PRELIMS 2014 9 Group C came up with Hypothsis : ‘Tourism has a negative impact on the environment in Chinatown.’ The group decided to use a bi-polar survey to investigate the hypothesis. Design a bi-polar survey that the students can use how it can be used to investigate the Hypothesis. [4] (a) ·        Table with positive and negative aspects ·        Scoring system/ Scale included – at least a 5 point scale (ie: -2 to +2) ·        At least 2 relevant criteria to be tested (litter, noise, pedestrain count, tourist adverts and signs, well – kept buildings) ·        To be done at all four sites ·        Added and averaged for all four sites ·        Positive score suggests minimal environmental impacts and negative scores suggests large environmental impacts (b) The school has a Stevenson Screen located permanently at Site A. Suggest reasons why Site A is an ideal location for a Stevenson Screen.                                                                                                                                     [2] ·        It is relatively far away from buildings which might affect the airflow and cause inaccuracies in the data collected ·        It is covered with grass which does not absorb heat compared to other types of ground surfaces. This also helps to ensure the accuracy of the data collected. (c) For the rest of the sites, the students went to the sites at 8am and 3pm every day to take the air temperature measurements. They also recorded the information at Site A at the same time. The information collected was recorded in Table 3.  Table 3 Calculate the three day site average for Site H in Table 2B and use the results to complete the scatter graph which shows the three day average temperature at each site. (A best fit line should also be used to complete the graph.)                                                                                                                                                                          [4] ·        X = 5.8°C (1m) ·        Accuracy of data plotted (3@2m, 1@1m, 2@1m) ·        Labelling of Site (all sites @ 1m) ·        Best fit line (1m) ANGLICIAN HIGH SCHOOL PRELIMS 2014 10    (a) Describe how the students might have collected the data.                                                                    [3]                Reserve 1 mark for type of survey: ·        The students could carry out a questionnaire /  interviews. 2 marks on any of the following points for description of an appropriate method: ·        Sampling method – systematic (20-30 years old) / random sampling ·        How many people to survey – 50 visitors ·        Where to carry it out – along a busy road in Orchard Road ·        When to carry it out – during peak periods, perhaps during lunch at 11.30 – 2.30pm ·        Types of questions in the questionnaire – choice or open-ended questions             A group of Secondary 4 students conducted an investigation on the trends in tourism in Singapore.  The hypothesis they investigated was: Tourists from countries that are farther away tend to spend more days in Singapore.  They carried out a survey of visitors to Orchard Road in order to prove the hypothesis.  Number of visitors to Orchard Road and their length of stay Origin of visitors No. of visitors interviewed Length of stay No overnight stay 1 – 3 nights 4 – 7 nights 8 – 14 nights United States of America 7 0 2 4 1 United Kingdom 6 0 1 3 2 Japan 10 0 4 5 1 Australia 5 0 1 4 0 India 9 0 3 6 0 Malaysia 8 3 5 0 0 Indonesia 5 1 4 0 0 Table 4 (b)    The students wanted to map the information shown in Table 4.  Briefly describe a suitable method to show this information on a map.                                                                                                                               [2] *mark by point Reserve 1 mark for type of map: ·        The students can map it on a desire line map/flow line map                                                 1 mark for description: ·        The students can use the desire lines of proportional width to represent where the visitors to Singapore come from as well as how many days they stay in Singapore (instead of number of people).
