Topic 6: Fieldwork enquiry stage 2 - Fieldwork techniques and methods explained
Fieldwork data collection relies on direct observation and measurement techniques matched to sampling strategies (random, systematic, stratified).
Read the full explanation
Observation records visible geographical features through qualitative notes (land-use mapping, annotated field sketches, photographs) and quantitative counts (pedestrian or traffic tallies using recording sheets). Measurement uses instruments to quantify physical variables (river velocity with flow meters, sediment size with callipers, slope angle with clinometers) and perceptual variables (bipolar environmental quality surveys, questionnaires). Methods must be selected to produce reliable, representative data capable of answering the enquiry question.
Your focus
- Identify observation and different kinds of measurement used in fieldwork.
- Describe how a named fieldwork technique is carried out and recorded.
- Evaluate the strengths and limitations of a named fieldwork technique.

Marking Points
- Distinguishes between observation methods (recording visual features, land use, or tallies of people/traffic) and instrument measurements (quantifying variables like velocity, gradient, or sediment size).
- Recognises that direct observation can produce both qualitative data (sketches, descriptive field notes) and quantitative data (tally counts, frequency recordings).
- Identifies appropriate measuring instruments for physical variables (e.g. flow meter for velocity, clinometer for slope angle, callipers for pebble axis).
- Identifies methods for measuring perceptual or human variables, such as environmental quality surveys (EQS) and bipolar rating scales.
- Explains how sampling techniques (systematic, stratified, random) are applied to select observation and measurement sites.
Examiner Tips
- 💡Clearly state the specific instrument and units of measurement for any physical fieldwork method described.
- 💡Recognise tally charts and frequency counts as observational recording methods.
- 💡Explain both the advantages and limitations of observational and measurement methods in fieldwork.
Common Mistakes
- Wrongly assumes that observation cannot involve numbers; direct observation frequently records numerical data such as pedestrian or traffic tallies.
- Confuses subjective perception scoring (e.g. environmental quality scales) with objective physical measurements (e.g. water speed with a flow meter).
- Fails to specify the tool or instrument used when describing a measurement technique.
