🎯 Common Question Types and How to Approach Them:
- "Justify your choice of presentation technique" (4–6 marks) — Use DECIDE. Name the data type (continuous/discrete/locational), name the technique, explain why the technique suits that data type, compare with at least one alternative and explain why it would be less appropriate. Mention a limitation of your chosen technique.
- "Describe the pattern shown" (2–4 marks) — Use specific figures: not "pebble size decreases" but "pebble size decreases from 42 mm at Site 1 to 11 mm at Site 5". Identify the overall trend AND any anomalies. Never use more than one sentence to describe before moving to explanation.
- "Suggest how the presentation could be improved" (2 marks) — Give a specific, targeted improvement, not a vague one ("collect more data" earns zero). Say what you would change and why it would help: "Adding error bars to each bar would show variability within sites, allowing the reader to judge whether the differences between sites are greater than the natural variability at each site."
- "Evaluate your presentation method" (6–8 marks) — Cover: (1) what the technique shows well, (2) what it hides or distorts, (3) whether it allowed your hypothesis to be tested, (4) how it could be improved, (5) whether an alternative technique would have been better. Use specific evidence from your own fieldwork throughout.
📝 Key Command Words Defined:
- Justify — give reasons for your decision; explain why the chosen approach is appropriate; compare with alternatives
- Evaluate — make a judgement about the quality, effectiveness, or appropriateness of something; include strengths AND limitations; reach a conclusion
- Describe the pattern — say what the presentation shows; use specific figures; identify the trend and anomalies
- Suggest — propose a plausible explanation or improvement; you do not need to be certain, but the suggestion must be geographically reasonable and specific
- Compare — identify both similarities AND differences between two things; use comparative language ("whereas", "in contrast", "both... but...")
⚠️ Common Mistakes to Avoid:
- Joining dots on a scatter graph (never do this — add a line of best fit instead)
- Forgetting units on graph axes (costs marks every time — "Pebble size (mm)" not just "Pebble size")
- Describing the pattern instead of analysing it (use "this suggests... because..." rather than "the graph shows that...")
- Saying "I used a bar chart because it was easy" — this is not a justification and earns zero marks
- Suggesting vague improvements ("I would collect more data") — always be specific about what you would change and why
- Using a pie chart to show change over time — pie charts cannot show time-series data; use a line graph
- Using a line graph for discrete categorical data (land uses, building types, named areas) — use a bar chart for discrete categories
- Failing to include a north arrow, scale bar, and legend on any map presentation
