Answer Key and Marking Scheme

Paper: Practice Paper 5 (Map, Graph & Data Skills) Total Marks: 50

Section A: Map Reading and Interpretation (15 marks)

Question 1

(a) State the six-figure grid reference of the trigonometrical station at Bukit Timah. [1]

Answer: 362875 (accept 362874–362876)

Marking notes:

1 mark for correct six-figure reference.
Must be six figures; four-figure reference scores 0.

(b) Measure the straight-line distance, in kilometres, between the jetty at Telok Ayer (GR 345872) and the summit of Bukit Timah. [2]

Answer: 3.3 km (accept 3.2–3.4 km)

Marking notes:

1 mark for correct measurement on map (6.6 cm at 1:50,000 scale).
1 mark for correct conversion to kilometres (6.6 cm × 0.5 km/cm = 3.3 km).
Allow ±0.1 km tolerance for measurement variation.

(c) Calculate the gradient between the jetty at Telok Ayer (elevation 0 m) and the summit of Bukit Timah (elevation 165 m), given that the straight-line distance is 3.3 km. Express your answer as a ratio. [2]

Answer: 1:20

Working:

Vertical difference = 165 m − 0 m = 165 m
Horizontal distance = 3.3 km = 3300 m
Gradient = 165 : 3300 = 1 : 20

Marking notes:

1 mark for correct vertical difference and conversion of units.
1 mark for correct ratio in simplest form.
Accept 1:20 or 1/20.

Question 2

(a) Describe the settlement pattern shown in the northeastern part of the map extract. [2]

Answer: The settlement pattern is linear/dispersed, with buildings arranged along the main road/river. Settlements are scattered rather than clustered, following the transport route.

Marking notes:

1 mark for identifying the pattern (linear/dispersed).
1 mark for describing the arrangement (along road/river, scattered).

(b) Suggest two reasons why the settlement pattern you described in 2(a) has developed in this area. [4]

Answer:

The presence of the main road provides accessibility and transport links, encouraging linear development along the route for convenience and trade.
The flat/low-lying terrain along the river valley is suitable for building, while steeper slopes elsewhere limit settlement expansion, concentrating development along the valley floor.

Marking notes:

2 marks for each well-explained reason (1 mark for identification, 1 mark for explanation).
Accept other valid reasons: availability of water from the river, fertile alluvial soil for agriculture, avoidance of swampy/marshy areas shown on the map.

Question 3

(a) Identify the direction of flow of the river in grid square 3586. [1]

Answer: South / South-southeast / Southeast

Marking notes:

1 mark for correct compass direction.
Determined by contour lines (river flows from higher to lower elevation).

(b) Using map evidence, describe three characteristics of this river and its valley. [3]

Answer:

The river meanders/has bends — shown by the winding course of the river on the map.
The valley has gentle slopes — indicated by widely spaced contour lines on either side of the river.
The river has tributaries joining it — shown by smaller streams converging with the main river channel.

Marking notes:

1 mark for each characteristic with supporting map evidence.
Accept other valid characteristics: river flows through flat floodplain (wide valley floor), presence of river cliffs (closely spaced contours on outer bends), river is narrow (single blue line).

Section B: Graphical and Statistical Skills (20 marks)

Question 4

(a) Describe the overall trend in visitor arrivals to Singapore between 2010 and 2024. Support your answer with data from Figure 2. [3]

Answer: Overall, visitor arrivals to Singapore increased significantly from 2010 to 2024. Arrivals rose from approximately 11.6 million in 2010 to a peak of around 19.1 million in 2019, before a sharp decline to about 2.7 million in 2020. Arrivals then recovered to approximately 16.5 million by 2024. Despite the 2020 disruption, the long-term trend shows growth.

Marking notes:

1 mark for identifying the overall increasing trend.
1 mark for citing specific data points (start, peak, and end values).
1 mark for noting the anomaly (2020 decline) and subsequent recovery.

(b) Identify one year in which there was a significant anomaly in the trend. Suggest a possible reason for this anomaly. [2]

Answer: 2020. The sharp decline in visitor arrivals (from 19.1 million in 2019 to 2.7 million in 2020) was likely due to the COVID-19 pandemic, which led to global travel restrictions, border closures, and reduced international tourism.

Marking notes:

1 mark for identifying 2020 as the anomalous year.
1 mark for a plausible reason (COVID-19 pandemic, travel restrictions).

Question 5

(a) Suggest a suitable type of graph for this purpose. Justify your choice. [2]

Answer: A bar chart (or column graph) showing percentage change from the previous year. This type of graph is suitable because it clearly shows positive and negative changes for each year, allowing easy visual comparison of year-on-year fluctuations. Bars above the axis represent growth, while bars below represent decline.

Marking notes:

1 mark for suggesting a bar chart (or waterfall chart).
1 mark for justification (shows positive/negative change, easy comparison).

(b) Describe how the student could construct this graph. [3]

Answer:

Calculate the percentage change for each year using the formula: [(Current year − Previous year) ÷ Previous year] × 100.
Draw the x-axis (years, 2011–2024) and y-axis (percentage change, with positive values above zero and negative values below zero).
Plot bars for each year — bars extending upward for positive growth, downward for negative growth. Label axes clearly and provide a title.

Marking notes:

1 mark for describing the calculation method.
1 mark for describing axis construction (including negative values).
1 mark for describing plotting and labelling.

Question 6

(a) Using Figure 3, compare the use of public transport by tourists in Singapore and Bangkok. [2]

Answer: A higher proportion of tourists used public transport in Singapore compared to Bangkok. In Singapore, public transport accounted for approximately 55% of tourist transport, while in Bangkok it accounted for approximately 35%. The difference is about 20 percentage points.

Marking notes:

1 mark for stating which destination has higher usage.
1 mark for supporting with data (percentages or comparison).

(b) Explain one advantage and one disadvantage of using a divided bar chart to present this type of data. [4]

Answer:

Advantage: A divided bar chart allows easy visual comparison of the relative proportions of different transport modes within each destination, as the total bar length represents 100%. This makes it simple to see which mode dominates in each location.
Disadvantage: It is difficult to compare individual segments across different bars, especially for smaller categories, because the segments are not aligned on a common baseline. For example, comparing the "walking" segment across Singapore, Bangkok, and Bali requires estimating different starting points.

Marking notes:

2 marks for a well-explained advantage (1 mark for identification, 1 mark for explanation).
2 marks for a well-explained disadvantage (1 mark for identification, 1 mark for explanation).

Question 7

(a) Calculate the percentage of tourists who used private transport in Bali, given that 240 out of 800 tourists surveyed used private transport. [1]

Answer: 30%

Working: (240 ÷ 800) × 100 = 30%

Marking notes:

1 mark for correct answer. Accept 30% or 30.

(b) The students who collected this data surveyed 800 tourists in Bali, 600 in Bangkok, and 500 in Singapore. Evaluate whether the sample sizes are sufficient to draw reliable conclusions about tourist transport preferences in each destination. [3]

Answer: The sample sizes are moderately sufficient but have limitations. A sample of 800 in Bali is reasonably large and likely to provide reliable results if randomly selected. However, the samples of 600 in Bangkok and 500 in Singapore are smaller, which increases the margin of error. The unequal sample sizes also make direct comparisons between destinations less reliable — differences in results could partly reflect sampling variation rather than real differences in transport preferences. To improve reliability, the students should aim for equal, larger sample sizes (e.g., 1000 per destination) and ensure random sampling.

Marking notes:

1 mark for acknowledging that larger samples are generally more reliable.
1 mark for identifying the issue of unequal sample sizes affecting comparability.
1 mark for suggesting improvement or noting the limitation of smaller samples.

Section C: Data Interpretation and Fieldwork Skills (15 marks)

Question 8

(a) State a suitable hypothesis for this investigation. [1]

Answer: "Environmental quality increases with increasing distance from the city centre" OR "Sites further from the city centre have higher environmental quality scores than sites closer to the city centre."

Marking notes:

1 mark for a clear, testable hypothesis stating the expected relationship between distance and environmental quality.
Hypothesis must be directional (not a question).

(b) Describe the relationship between distance from the city centre and environmental quality score shown in Figure 4. Support your answer with data. [3]

Answer: There is a positive relationship between distance from the city centre and environmental quality score. Sites closer to the city centre (e.g., 1–3 km) have lower EQI scores of around 8–12, while sites further away (e.g., 8–10 km) have higher scores of around 18–22. The relationship is generally consistent, with EQI scores increasing as distance increases, though there may be some minor fluctuations.

Marking notes:

1 mark for identifying the positive relationship.
1 mark for citing data from both near and far sites.
1 mark for noting the general consistency of the trend.

Question 9

(a) Explain one strength of using an index to measure environmental quality. [2]

Answer: An index combines multiple indicators into a single score, providing a comprehensive and holistic measure of environmental quality. Instead of assessing air quality, noise, litter, green space, and building condition separately, the EQI summarises overall environmental quality in one number, making it easier to compare sites and identify patterns.

Marking notes:

1 mark for identifying the strength (combines multiple indicators, comprehensive).
1 mark for explaining why this is useful (easier comparison, holistic assessment).

(b) Suggest one limitation of the students' sampling method if they selected sites only along one main road radiating from the city centre. [2]

Answer: Selecting sites only along one main road introduces bias because environmental conditions along that road may not be representative of the entire city. For example, a main road may have higher traffic, noise, and air pollution than residential side streets at the same distance from the city centre. This means the results may not accurately reflect the general relationship between distance and environmental quality across the whole city.

Marking notes:

1 mark for identifying the limitation (bias, not representative).
1 mark for explaining why this affects the results (specific road conditions differ from general patterns).

Question 10

(a) With reference to the fieldwork investigation described above, suggest how the students could improve the reliability of their data collection. [3]

Answer:

Increase the number of sampling sites: Instead of 10 sites, use 20 or more sites at varying distances to provide a more detailed and representative picture of environmental quality across the city.
Use multiple transects: Select sites along several roads radiating from the city centre in different directions (e.g., north, south, east, west) rather than just one road, to capture spatial variation and reduce bias.
Repeat measurements: Take EQI readings at each site on multiple days and at different times to account for daily and seasonal variations (e.g., traffic levels vary by time of day). Calculate average scores for greater reliability.

Marking notes:

1 mark for each well-explained suggestion (up to 3 marks).
Accept other valid suggestions: use multiple observers and calculate inter-observer reliability, use calibrated instruments instead of subjective scoring, ensure random selection of sites within distance bands.

(b) The students concluded that "environmental quality improves with increasing distance from the city centre." Evaluate the validity of this conclusion. [4]

Answer: The conclusion has some validity but is an oversimplification. The data in Figure 4 does show a general positive trend between distance and EQI scores, supporting the students' conclusion. However, several factors limit its validity:

Sampling bias: Sites were selected along only one main road, which may not represent the entire city. Environmental quality patterns may differ in other directions (e.g., industrial areas may be located at varying distances).
Correlation vs. causation: The relationship may be influenced by other factors correlated with distance, such as land use (commercial/industrial near centre vs. residential further out), population density, or planning policies, rather than distance itself.
Exceptions and anomalies: The trend may not be uniform — some distant sites may have poor environmental quality (e.g., near industrial estates or landfills), and some central sites may have good quality (e.g., near parks or in well-planned districts).

Therefore, while the general trend supports the conclusion, it is not universally valid. A more accurate conclusion would be: "In the area studied, environmental quality tends to improve with distance from the city centre, but this pattern may vary in other parts of the city and is influenced by multiple factors beyond distance alone."

Marking notes:

1 mark for acknowledging the supporting evidence (general trend).
1 mark for identifying sampling limitations (one road, not representative).
1 mark for discussing alternative factors (land use, other variables).
1 mark for a balanced, nuanced conclusion that qualifies the original statement.
