Section C: Statistical Analysis and Fieldwork Data

Students conducted a fieldwork investigation into river quality. They collected data on water velocity and pollution levels at five sites downstream from a factory.

Table 1: River Data Collection Results

Site	Distance from Source (km)	Velocity (m/s)	Pollution Index (1-10, 10=High)
1	2.0	0.4	2
2	5.0	0.6	3
3	8.0	0.9	8
4	11.0	1.1	7
5	14.0	1.3	4

11. Calculate the mean velocity of the river across the five sites. Show your working. [2]

14. Evaluate the reliability of the Pollution Index data collected at Site 3. Consider the method of data collection (visual observation of debris) in your answer. [3]

15. Suggest one improvement to the sampling strategy that would make the conclusions about river pollution more valid. [1]

Section D: Source-Based Data Evaluation

Study Fig. 4, a photograph of a urban heat island effect measurement exercise, and Fig. 5, a table of results.

Fig. 4: Photograph Description Students are using digital thermometers to measure air temperature at 1.5m height in three locations: a concrete car park, a grassy park, and a wooded area. It is 2:00 PM on a sunny day.

Fig. 5: Temperature Results (°C)

Location	Reading 1	Reading 2	Reading 3	Mean
Car Park	32.0	32.5	31.8	32.1
Park	28.0	27.5	28.2	27.9
Woods	26.0	26.2	25.8	26.0

16. Why did the students take three readings at each location instead of just one? [1]

17. Calculate the temperature difference between the Car Park and the Woods. [1]
Answer: __________________________ °C

18. Explain how the surface materials in the Car Park contribute to the higher temperature recorded compared to the Woods. [2]

19. The students concluded that "Urban areas are always hotter than rural areas." Critique this conclusion based on the data provided in Fig. 5. [2]

20. Suggest one additional variable that should have been controlled during this investigation to ensure the results were comparable. [1]

Answers

TuitionGoWhere Practice Paper - Geography O-Level (Answer Key)

Version: 2 of 5
Subject: Geography (2279)
Topic: Map, Graph & Data Skills

Section A: Map Skills and Spatial Analysis

1. Grid Reference
Answer: 442 684 (Accept 441-443 683-685 depending on precise map interpretation, but standard answer key assumes specific point).
Marking Note: 1 mark for correct 6-figure reference. First 3 digits for Easting, last 3 for Northing.

2. Distance Measurement
Answer: Approx 3.4 – 3.6 km.
Marking Note: 1 mark for correct measurement within tolerance (±0.1 km). Students must use the scale bar or grid squares (1km x 1km).

3. Relief Description
Answer:

The land is hilly/steep.
Height ranges from approx 50m to over 100m (contours are close together).
Marking Note: 1 mark for describing height/elevation, 1 mark for describing slope/gradient (close contours = steep).

4. Settlement Location Reasons
Answer: Any two of:

Protected natural harbor/bay (sheltered from waves).
Flat land available for construction (contours are sparse).
Access to water/river for transport or fresh water.
Junction of transport routes (if roads visible).
Marking Note: 1 mark per valid reason supported by map evidence.

5. Bearing Calculation
Answer: Approx 030° – 040°.
Marking Note: 1 mark for correct method (drawing North line at Post Office), 1 mark for accurate measurement. Accept ±3°.

Section B: Graphical Representation and Interpretation

6. Annual Temperature Range
Answer: 3°C (29°C - 26°C).
Marking Note: 1 mark for correct calculation.

7. Rainfall Pattern
Answer:

Rainfall is high throughout the year (no dry month).
There is a slight decrease in the middle of the year (June/July) and higher rainfall at the start and end of the year.
Marking Note: 1 mark for identifying high annual total/consistency, 1 mark for noting the specific dip/peak pattern.

8. Graph Type Suggestion
Answer:

Graph Type: Bar Graph.
Reason: Bar graphs are best for comparing discrete categories (months) or showing magnitude of data (volume) clearly.
Marking Note: 1 mark for "Bar Graph", 1 mark for valid reason (comparison/discrete data). Line graphs are acceptable if justified as showing trend, but Bar is preferred for rainfall volume comparison.

9. Relationship Description
Answer:

There is a negative/inverse relationship.
As temperature decreases (e.g., in July), visitor numbers increase.
Marking Note: 1 mark for identifying the inverse relationship, 1 mark for supporting with data reference (e.g., coolest month has highest visitors).

10. Proportion Graph Suggestion
Answer:

Graph Type: Pie Chart.
Explanation: Pie charts are specifically designed to show parts of a whole (proportions/percentages) clearly.
Marking Note: 1 mark for "Pie Chart", 1 mark for explanation referencing "parts of a whole" or "proportions".

Section C: Statistical Analysis and Fieldwork Data

11. Mean Velocity
Answer: 0.86 m/s.
Working: (0.4 + 0.6 + 0.9 + 1.1 + 1.3) ÷ 5 = 4.3 ÷ 5 = 0.86.
Marking Note: 1 mark for correct sum, 1 mark for correct division/answer.

12. Anomaly Identification
Answer:

Anomaly: Site 3 (or Site 4, but Site 3 is the peak).
Reason: Possible illegal dumping at that specific spot, or measurement error, or a tributary entering with polluted water.
Marking Note: 1 mark for identifying Site 3 (highest pollution despite being mid-stream), 1 mark for plausible reason.

13. Trend Description
Answer:

Positive correlation.
As distance from source increases, velocity increases.
Marking Note: 1 mark for direction of correlation, 1 mark for describing the variables' relationship.

14. Reliability Evaluation
Answer:

The data may be unreliable because "visual observation" is subjective.
Different students might interpret "debris" differently.
It lacks precision compared to chemical testing.
However, taking multiple samples could improve it (but the prompt implies single visual check).
Marking Note: 1 mark for identifying subjectivity/qualitative nature, 1 mark for explaining impact on reliability, 1 mark for valid judgment (e.g., "low reliability due to lack of standardization").

15. Sampling Improvement
Answer:

Increase sample size (more sites).
Repeat data collection at different times/days.
Use standardized water testing kits instead of visual observation.
Marking Note: 1 mark for any valid methodological improvement.

Section D: Source-Based Data Evaluation

16. Multiple Readings
Answer: To calculate a mean/average and reduce the impact of anomalies/random errors.
Marking Note: 1 mark for referencing accuracy/reliability/mean calculation.

17. Temperature Difference
Answer: 6.1°C (32.1 - 26.0).
Marking Note: 1 mark for correct calculation.

18. Surface Material Explanation
Answer:

Concrete/asphalt has low albedo (absorbs more solar radiation).
Concrete has high thermal capacity/conductivity, storing heat and releasing it.
Lack of vegetation means no cooling from evapotranspiration.
Marking Note: 1 mark for absorption/albedo reference, 1 mark for lack of vegetation/evapotranspiration.

19. Conclusion Critique
Answer:

The conclusion is too general/absolute ("always").
The data only shows one point in time (2:00 PM) and one day.
Temperatures might differ at night or in different seasons.
Only three locations were tested, which is not representative of all urban/rural areas.
Marking Note: 1 mark for identifying the generalization error, 1 mark for referencing limited data scope (time/sample).

20. Controlled Variable
Answer:

Time of day (already controlled, but could mention "same time").
Height of thermometer (controlled at 1.5m).
Weather conditions (sunny/windy).
Shade vs. direct sunlight exposure.
Marking Note: 1 mark for any valid variable that affects temperature measurement (e.g., "Ensure all thermometers were in direct sunlight" or "Shielded from wind").
