This page delves deeper into specific geographical skills and techniques, as well as outlining the route to geographical inquiry.

Advanced Graphical Techniques

• Bar charts show discrete data, while line graphs display continuous data
• Compound line graphs and bar charts can be used to compare multiple data sets

Highlight: Radar diagrams allow comparison of different sites on the same graph, often used for environmental quality assessments. If the diagram goes above or below zero, it's called a bi-polar analysis.

Example: Kite diagrams are frequently used to show the abundance of different species along a transect.

The Route to Geographical Inquiry

1. Aims/hypothesis
2. Methodology
3. Data collection
4. Data presentation
5. Data analysis
6. Conclusion

Definition: Primary data is data you have collected yourself, while secondary data is obtained from other sources.

Sampling Methods

Sampling should be unbiased, accurate, practical, and representative. Methods include:

• Random sampling: Most accurate method as it has no bias
• Systematic sampling: Quicker and easier, selecting every nth person
• Stratified sampling: Selecting enough people from each demographic to reflect the larger population

Vocabulary: Random sampling is considered the most accurate method as it eliminates bias.

Practical Fieldwork Techniques

Examples of geographical fieldwork techniques include:

• Measuring sediment size
• Creating cross profiles of rivers
• Measuring stream velocity using floats like orange peel

Example: To measure stream velocity, geographers might use a float such as orange peel and time its movement over a set distance.

This comprehensive guide to cartographic and diagrammatic techniques for geography exams provides students with essential geographical skills and knowledge needed for success in their GCSE geography studies and beyond.

This page introduces various cartographic and diagrammatic techniques for geography exams, focusing on three main categories: cartographic, graphical, and diagrammatic methods.

Cartographic Techniques

Cartographic techniques involve the creation and use of maps to represent geographical data. Some key types of maps in geography include:

• Annotated maps
• Located graphs and charts
• Flow/desire line maps
• Choropleth maps
• Isoline maps
• Topological maps

Definition: A desire line map shows where people have travelled from to reach a particular destination.

Definition: A flow line map uses different line widths to represent the volume of people migrating from one place to another.

Highlight: Spheres of influence use proportional circles to illustrate the impact of a place on its surroundings, such as comparing a small corner shop to a large theme park.

Graphical Techniques

Graphical techniques involve various types of graphs and charts used to present geographical data:

• Bar graphs and histograms
• Pie charts
• Stacked/compound bar charts
• Line graphs
• Scatter graphs
• Pictograms

Example: Located maps plot graphs at different points on a map to measure various values for different parts of a town.

Diagrammatic Techniques

Diagrammatic techniques include:

• Field sketches
• Diagrams
• Annotated photos
• Spider diagrams for qualitative (word) data

Vocabulary: Isoline maps join up different parts of an area with the same value, such as rainfall levels or pedestrian counts.

Vocabulary: Topological maps show a simplified version of reality, like the London Underground map.

Vocabulary: Choropleth maps use color on a map, with darker colors generally representing higher data values.
