Topic Summary: Presenting Geographical Data
Key Techniques
- Bar chart — discrete categories, comparison
- Line graph — continuous data over time/distance
- Scatter graph — relationship between two continuous variables
- Choropleth — relative values across areas (spatial)
- Dispersion diagram — spread of data at each site
- Kite diagram — abundance along a transect
- Flow map / desire lines — direction and volume of movement
- Pie / proportional circle — proportions of a total
- Radar / spider diagram — multi-variable EQS comparison
Key Terms
- Choropleth — shading shows relative values per area
- Isoline — connects equal values on a map
- Desire line — straight line showing movement direction + volume
- Dispersion diagram — plots all values to show spread
- Kite diagram — transect abundance, symmetrical around centre
- Line of best fit — trend line through scatter graph points
- Spearman's rs — numerical measure of correlation strength (−1 to +1)
- Proportional circle — circle area ∝ value
Decision Rules
- Two continuous variables + relationship test → Scatter graph
- Discrete categories + comparison → Bar chart
- Continuous over time/distance → Line graph
- Spatial distribution across areas → Choropleth
- Proportions of a total → Pie / proportional circle
- Spread of data at sites → Dispersion diagram
- Species along transect → Kite diagram
- Movement direction + volume → Flow map
- Multi-variable site comparison → Radar diagram
Must-Know Analysis Phrases
- "This suggests..." (interpretation)
- "This is consistent with..." (theory link)
- "This could be because..." (causal explanation)
- "An anomaly at [X] may reflect..." (outlier explanation)
- "The data shows a strong negative correlation (rs = X)..." (statistical evidence)
- "A limitation of this technique is..." (evaluation)
- "This is more appropriate than [alternative] because..." (justification)
- Always include specific values in brackets: "(52 vs 156 vehicles/hour)"
