Coastal systems and landscapes - 3.1.3.5 Quantitative and qualitative skills explained
To master coastal landscape systems, you must integrate both quantitative and qualitative fieldwork skills.
Read the full explanation
Observation skills involve systematically recording coastal features, such as sketching cliff profiles or annotating photographs of wave types. Measurement skills require using equipment accurately, like ranging poles and clinometers to measure beach profiles. Geospatial mapping skills involve locating these measurements using GIS software to analyse spatial patterns of erosion or deposition. Finally, you must manipulate this field data and apply statistical skills, such as calculating the mean pebble size or using Spearman's rank correlation to test the relationship between sediment size and distance from the shoreline.
Your focus
- Demonstrate accurate observation and measurement skills using appropriate fieldwork equipment in a coastal environment.
- Apply geospatial mapping techniques to represent and analyse spatial data collected during fieldwork.
- Perform data manipulation and statistical analysis on field measurements to draw valid geographical conclusions.
Coastal systems and landscapes - 3.1.3.5 Quantitative and qualitative skills exam tips
Examiner Tips
- 💡When evaluating fieldwork, explicitly mention the equipment used for measurements and assess its reliability and potential for human error.
- 💡Practise interpreting statistical results in the context of coastal systems, such as explaining what a standard deviation reveals about sediment sorting.
- 💡Ensure you can justify your choice of data manipulation techniques, explaining why a specific graph or statistical test was appropriate for your field measurements.
Common Mistakes
- Treating qualitative data as less valuable than quantitative data. Correction: Recognise that qualitative observations, like field sketches and annotated photographs, provide essential context that numbers alone cannot capture.
- Failing to link statistical tests to the original geographical purpose. Correction: Always explain what a statistical result, such as a significant correlation, actually means for the coastal processes being studied.
- Using geospatial mapping merely for presentation rather than analysis. Correction: Use GIS to identify spatial patterns and relationships, not just to plot data points on a map.
