# Fieldwork That Answers a Question

Plan fieldwork around a question that observations can test. Define what to measure, choose sites and times, justify the sample, and identify possible biases while keeping the work safe.

## Ready when they can

- Turn a vague interest into a question that observations can test
- Choose a sampling method and justify it against the alternatives for that site
- Identify two things about your method that could bias the result, and say how you would reduce each

## Lesson: Planning fieldwork to test a prediction

We now turn from world trade to local fieldwork. Earlier fieldwork used maps, tallies and measurements. Plan a test before collecting more data. To study litter, count equal-sized plots near food shops and farther away at noon. Decide what counts as one item. Similar counts would not support a prediction of more litter near shops. Questions about people's views need a survey instead. A sample without a clear difference does not prove there is no pattern elsewhere.

A sample covers part of a defined study area. For a simple random sample, list eligible spots and use a chance process giving each an equal chance. Systematic sampling uses fixed gaps, preferably after a random start. Repeated features can match the gaps. Stratified sampling divides the area into zones and samples within each. A whole-site estimate must also account for the zones' different sizes.

*(drawing: A start at 4 m followed by gaps of 8 m gives systematic sampling stations.)*

Justify the method using the question and site. To compare dunes, a car park and a pier, sample within every permitted zone; a small random sample might miss one. Along a path, fixed gaps spread stations along its length, while a small random sample may leave uneven gaps. State a limitation too: repeating features may line up with fixed stations. No method is best for every enquiry.

Name possible biases and a change for each. Dry-day visitor counts may miss wet-weather use; repeat at planned times in varied weather when conditions are safe. A leading question suggests an answer and may influence replies. Replace it with neutral wording. Pilot the questionnaire by testing it on a small group, then revise it. A pilot helps find problems but does not remove every bias.

Safety and permission come before coverage. Do not enter unsafe or restricted ground to complete a sample. Define an approved study area, then choose stations across it rather than only beside the easiest path. Record excluded places. If they differ from the sampled ground, limit conclusions to the area you could study instead of claiming to describe the whole site.

**Recap.** Define the question and study area, justify the sample, keep the work safe, and report possible biases and limits.
