A-Level Geography revision: Fieldwork and Data Collection. Learning objectives, key points, worked examples and practice questions across AQA, Edexcel, OCR, WJEC and CCEA.
📌 Key Points
Key Fact: Enquiry: hypothesis (testable), sub-questions, risk assessment, ethical considerations (consent, privacy)
Key Fact: Sampling: random (unbiased), systematic (interval), stratified (proportional subgroups), opportunistic (pragmatic)
Key Fact: Primary: questionnaires, EQ surveys, sediment analysis, velocity, infiltration; Secondary: OS maps, census, Met Office, academic papers
Key Fact: Presentation: proportional circles, choropleth, scatter with trend line, rose diagrams, cross-sections
Key Fact: Stats: Spearman's (correlation, ordinal), Chi-squared (categorical association), Mann-Whitney (difference, ordinal)
Key Fact: Evaluation: limitations (sample size, bias, equipment), reliability (repeatable), validity (measures what intended)
🎯 Learning Objectives
- Design geographical enquiries: hypothesis, aims, risk assessment, ethics
- Select appropriate sampling: random, systematic, stratified, opportunistic
- Collect primary data (surveys, measurements, observations) and secondary data (GIS, census, reports)
- Present data: graphs (bar, line, scatter, choropleth), maps, annotated photos, cross-sections
- Analyse: statistical tests (Spearman's, chi-squared, Mann-Whitney), qualitative coding
- Conclude and evaluate: limitations, reliability, validity, improvements
💡 Worked Example
Exam-Style Question
Question: Design a hypothesis and sampling strategy to investigate how footpath erosion varies with distance from a car park in a national park
Model Answer:
Hypothesis: Footpath erosion decreases with distance from car park due to visitor pressure decay. Systematic sampling: measure path width, depth, vegetation cover every 50m along 1km transect. Risk: weather, terrain. Ethics: minimise disturbance
❓ Practice Questions
Questions:
- Write a hypothesis for river velocity vs distance downstream
- Choose sampling for urban land use survey
- Select graph for population vs distance from CBD
- Explain when to use Spearman's vs Chi-squared
- Identify limitations of a given fieldwork method
