For one of your fieldwork enquiries, justify one method of primary data collection you used.
Justify means: Give reasons and evidence to support a choice or a decision.
Level 1 (Basic)· 2/6 marks (band 1–2)
We did an environmental quality survey. We gave each place a score. It was a good method.
Why this level: Names a method but doesn't explain how it was done or why it suited the enquiry. To reach Level 2: describe the method and link it to the hypothesis. In the exam, use the details of your own enquiry.
Level 2 (Clear)· 4/6 marks (band 3–4)
We used an environmental quality survey, scoring ten things, such as litter, noise and green space, from 1 to 5 at each of 22 sites. It suited our hypothesis, that quality improves away from the town centre, because it turned each site into a score out of 50 that could be compared.
Why this level: Clear description of the method, linked to the hypothesis. To reach Level 3: explain how it was made reliable and include a limitation. In the exam, use the details of your own enquiry.
Level 3 (Detailed)· 6/6 marks (band 5–6)
We used an environmental quality survey, scoring ten things, such as litter, noise, traffic and green space, from 1 to 5 at each of 22 sites along a line out of the town centre. It suited our hypothesis, that environmental quality improves away from the town centre, because it turned each site into a score out of 50, so sites could be compared and plotted against distance. Using the same survey sheet and criteria at every site made it fair, so the scores could be compared. However, scoring is subjective, so two people might score the same site differently, and it only shows the site at the time of the visit.
Why this level: Detailed description of the method, a clear justification linked to the hypothesis, steps for reliability and a limitation. This is Level 3. In the exam, use the details of your own enquiry.
