Section A: Research Design and Methodology (10 Marks)

1. A group of students is conducting a fieldwork investigation into the effectiveness of coastal management strategies at East Coast Park. They formulate the following hypothesis:
"Groynes are effective in trapping sediment and widening the beach on the updrift side."

Identify the Independent Variable in this hypothesis. [1]

2. Refer to the hypothesis in Question 1.

Identify the Dependent Variable in this hypothesis. [1]

3. Explain why it is important to formulate a hypothesis before starting data collection. [2]

4. The students decide to use systematic sampling to select sites along the coastline.

Define systematic sampling. [2]

5. State one advantage of using systematic sampling over random sampling for this specific coastline investigation. [2]

Section B: Data Collection Techniques (10 Marks)

6. State one potential disadvantage of systematic sampling in the context of a coastline investigation. [2]

7. To test their hypothesis, the students need to measure beach width.

Describe the method the students should use to measure beach width accurately, including the equipment needed. [2]

8. The students also need to measure sediment size.

Explain how the students should measure the size of pebbles using the longest axis method. [2]

9. The students design a questionnaire to assess public perception.

Construct one closed-ended question to ask visitors about their satisfaction with the beach width. [2]

10. Construct one open-ended question to ask visitors about their suggestions for improving the park. [2]

Section C: Data Processing and Presentation (10 Marks)

11. Explain why including both closed and open-ended questions is beneficial for data analysis. [2]

12. The students collected sediment size data (in cm) from five sites. The raw data for Site 3 is:
4.2, 3.8, 5.1, 4.5, 3.9, 4.8, 4.2, 5.0, 4.1, 4.4

Calculate the mean sediment size for Site 3. Show your working. [2]

Answer space

Answer: _______________ cm

13. Calculate the range of the sediment size for Site 3 using the data in Question 12. [2]

Answer space

Answer: _______________ cm

14. The students want to present the relationship between distance from the groyne (x-axis) and beach width (y-axis).

(a) Identify the most appropriate graph type to show this relationship. [1]

(b) Give one reason why this graph type is appropriate. [1]

15. If the students wanted to compare the frequency of different sediment size classes (e.g., 0-2cm, 2-4cm, 4-6cm) at a single site, which graph type would be most suitable? [2]

Section D: Analysis, Conclusion, and Evaluation (10 Marks)

16. State one essential feature that must be included in the title of any graph produced. [2]

17. The students plotted their data and found that beach width decreased as the distance from the groyne increased (moving downdrift).

Describe the trend shown in the data. [2]

18. Explain this trend using your knowledge of longshore drift and groyne function. [3]

19. Upon reviewing their work, the students identified several limitations.

(a) Identify one source of human error that might have affected the sediment size measurements. [1]

(b) Suggest one improvement to the data collection method to increase the reliability of the results. [2]

20. Explain why it is important to evaluate the limitations of fieldwork. [2]

Answers

Secondary 4 Geography Quiz - Fieldwork (Answer Key)

Total Marks: 40

Section A: Research Design and Methodology

Independent Variable: Presence of groynes / Distance from groyne / Location relative to groyne. [1]

Dependent Variable: Beach width / Amount of sediment trapped. [1]

It provides a clear focus for the investigation. [1]
It guides the selection of appropriate data collection methods and sites. [1]

Selecting samples at regular intervals (e.g., every 10 meters or every 5th person). [2]

It ensures even coverage of the entire study area/coastline. [1]
It is easier and faster to implement than random sampling in the field. [1]

Section B: Data Collection Techniques

It may miss important variations that occur between the regular intervals. [1]
If there is a periodic pattern in the environment that matches the sampling interval, the data may be biased. [1]

Equipment: Tape measure (or measuring wheel), ranging poles. [1]
Method: Place one pole at the high water mark (or base of sea wall) and another at the low water mark (or edge of water), stretch tape tightly between them, and record distance. [1]

Select a pebble randomly from the beach surface. [1]
Use calipers (or a ruler) to measure the longest dimension (length) of the pebble to the nearest mm/0.1cm. [1]

Example: "On a scale of 1-5, how satisfied are you with the current width of the beach?" (1 = Very Dissatisfied, 5 = Very Satisfied). [2]
(Must be closed-ended with fixed responses.)

10.

Example: "What changes would you suggest to improve the coastal management at this park?" [2]
(Must be open-ended allowing free text response.)

Section C: Data Processing and Presentation

11.

Closed questions allow for easy quantitative analysis and graphing. [1]
Open questions provide qualitative detail and insights that closed questions might miss. [1]

12.

Working: Sum = 4.2 + 3.8 + 5.1 + 4.5 + 3.9 + 4.8 + 4.2 + 5.0 + 4.1 + 4.4 = 44.0
Mean = 44.0 / 10 = 4.4 [1 for working, 1 for answer]
Answer: 4.4 cm

13.

Working: Largest value (5.1) - Smallest value (3.8) = 1.3 [1 for working, 1 for answer]
Answer: 1.3 cm

14.
(a)

Scatter graph (or Line graph). [1]

(b)

It shows the relationship/correlation between two continuous variables. [1]

15.

Histogram (or Bar chart). [2]
(1 mark for correct type, 1 mark for clarity/justification if required, but here simply identifying the correct graph for frequency distribution of classes is key.)

Section D: Analysis, Conclusion, and Evaluation

16.

The title must describe what is being shown, including the variables and the location. [1]
Example: "Graph showing the relationship between distance from groyne and beach width at East Coast Park." [1]

17.

There is a negative correlation / As distance from the groyne increases (downdrift), the beach width decreases. [2]

18.

Groynes act as barriers to longshore drift. [1]
Sediment is trapped on the updrift side (where the groyne is), causing accumulation and wider beaches. [1]
Less sediment reaches the downdrift side, leading to erosion or narrower beaches. [1]

19.
(a)

Parallax error when reading the ruler/calipers. [1]
Or: Inconsistent selection of pebbles (e.g., picking only large ones).

(b)

Increase the sample size (e.g., measure more pebbles at each site). [1]
This reduces the impact of anomalies and makes the mean more representative. [1]

20.

It helps to assess the validity and reliability of the conclusions drawn. [1]
It identifies areas for improvement in future investigations. [1]
