Unit 3: Fieldwork — Drawing Conclusions
Welcome to your study notes on Drawing Conclusions for CCEA GCSE Geography! You have collected your fieldwork data, created your tables, and drawn graphs. Now comes the exciting part: acting like a geographical detective to find out what your results actually mean.
In your 1-hour Unit 3 written exam (which is worth \(20\%\) of your overall GCSE), you will have your Fieldwork Statement and your Table of Data with you. Writing strong, top-mark conclusions is all about linking that real data back to your original aims and geographical theories.
Don't worry if this seems tricky at first — drawing conclusions follows a simple, repeatable formula that you can master with a bit of practice!
---1. What is a Geographical Conclusion?
A conclusion is a reasoned summary statement that answers your enquiry question. It tells the reader clearly whether your fieldwork results support or refute (disagree with) your original hypotheses, backed up by factual evidence and geographical understanding.
Think of it this way: Imagine you are a judge in a courtroom. You cannot just look at the clues and describe what they look like; you must make a clear final decision (a verdict) based on hard evidence and the rules of law!
Key Takeaway: A conclusion is not just a description of graphs. It is a reasoned decision about your hypothesis supported by numbers and geographical explanations.
---2. The 3-Step Formula for Testing Hypotheses
Whenever you are asked to draw a conclusion about one of your fieldwork hypotheses, follow this reliable S-E-E structure:
Step 1: Stance (Make your decision)
State clearly and directly whether your hypothesis is fully accepted / supported, partially supported, or rejected / unsupported.
Example: "Hypothesis 1—that river velocity increases downstream—is fully supported by the fieldwork data."
Step 2: Evidence (Quote your data with units)
Back up your decision with specific numerical proof directly from your Table of Data. Always include measurements, calculated averages, ranges, and correct units.
Example: "At Site 1 (the upper course), the mean velocity was \(0.32\text{ m/s}\), whereas downstream at Site 5, the mean velocity increased significantly to \(0.88\text{ m/s}\), representing an overall increase of \(0.56\text{ m/s}\)."
Step 3: Explanation (The geographical 'Why?')
Explain the science behind the trend using geographical concepts learned in Unit 1 or Unit 2 (such as the Bradshaw Model for river studies).
Example: "This trend occurred because as a river moves downstream, the channel becomes wider, deeper, and smoother. This reduces channel bed roughness and friction, creating a higher hydraulic radius and allowing water to flow faster."
Memory Trick: Remember S.E.E.
S = Stance (Accept, Partially Accept, or Reject)
E = Evidence (Numbers, comparisons, and units from your Table of Data)
E = Explanation (Geographical theory explaining why it happened)
Key Takeaway: Always state your stance clearly, quote specific numbers with units, and explain the physical or human geography processes driving the results.
---3. Spotting and Explaining Anomalies
An anomaly (or outlier) is a piece of data that does not fit the general pattern or expected geographical trend.
Did you know? Finding an anomaly does not mean your fieldwork failed! In real-world geography, nature rarely follows theoretical textbook models perfectly. Spotting and explaining anomalies shows top-level geographical thinking.
How to Address Anomalies in Your Exam:
1. Identify the Anomaly: Pinpoint exactly where the anomaly occurred using data from your table.
Example: "Although velocity generally increased downstream, an anomaly occurred at Site 3, where velocity dropped to \(0.21\text{ m/s}\), which was lower than Site 2 (\(0.45\text{ m/s}\))."
2. Suggest a Geographical Reason: What physical or human feature at that specific site could have caused this?
• Localized bed roughness: Large boulders or woody debris in the channel increased friction, slowing the water down.
• Channel shape: An unexpected localized widening of the channel decreased water depth and velocity.
• Human interference: A bridge support, artificial weir, or bank reinforcement disrupted natural flow.
3. Suggest a Methodological Reason: Could data collection limitations have caused the unusual reading?
• The flowmeter propeller may have been caught in riverbed weeds.
• An uncalibrated instrument or misread measurement during collection.
Key Takeaway: Never ignore anomalous results. Identify them using figures and give sensible geographical or practical reasons for why they happened.
---4. Answering the Overarching Enquiry Aim
At the end of your investigation, you must bring all your separate hypothesis conclusions together to answer your main fieldwork title or overarching aim.
• Bring Hypotheses Together: State how your combined findings (e.g., changes in channel width, depth, velocity, and bedload size) fit together.
• Compare with Established Models: Compare your overall conclusions with established geographical theory (such as the Bradshaw Model for physical river studies).
• Final Verdict: Provide a clear, concluding answer to the title stated in your Fieldwork Statement.
Key Takeaway: A complete conclusion connects the individual puzzle pieces (hypotheses) to reveal the big picture (the overall enquiry aim).
---5. Common Pitfalls to Avoid
Watch out for these common traps identified by CCEA examiners:
Trap 1: Writing a simple description instead of a conclusion
Don't just say: "The river got deeper and wider down the valley."
Instead say: "Hypothesis 1 is fully supported because the mean depth increased from \(0.14\text{ m}\) at Site 1 to \(0.62\text{ m}\) at Site 5..."
Trap 2: Forgetting data and units
Never make a statement without extracting actual figures from your Table of Data and including proper units such as \(\text{m}\), \(\text{cm}\), or \(\text{m/s}\).
Trap 3: Describing 'What' without explaining 'Why'
Always link your findings to geographical concepts (e.g., friction, discharge, hydraulic radius, or human activity) rather than just listing numbers.
Trap 4: Confusing Conclusions with Evaluation
Drawing a conclusion focuses on what the data shows in relation to your hypotheses. Evaluating focuses on how reliable and accurate your methods were. Keep your conclusions focused on interpreting the results!
Quick Revision Checklist
Before entering your Unit 3 examination, make sure you can:
[ ] State your hypotheses clearly and give a definitive verdict for each (Accepted / Partially Supported / Rejected).
[ ] Quote precise numerical values and correct units directly from your Table of Data.
[ ] Explain the geographical processes that caused your patterns.
[ ] Identify any anomalous data points and explain why they occurred.
[ ] Summarize all findings to answer your primary fieldwork aim.
