Revise Fieldwork Presentation and Evaluation Skills in Geographical Skills for GCSE Geography with 13 exam-style questions and 20 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 10 of 16 in this topic. Use this comparison to connect the idea to the wider topic before moving on to questions and flashcards.
⚖️ Strengths and Limitations of Key Presentation Techniques
| Technique | Strength | Limitation | Best Used When |
|---|---|---|---|
| Scatter graph | Shows correlation direction and strength; all individual data points preserved; can add line of best fit and rs value | Cannot prove causation; cannot show more than two variables at once; misleading if the relationship is non-linear | Testing the relationship between two continuous variables |
| Choropleth map | Spatial pattern across areas is immediately visible; easy to compare relative values between zones | Assumes uniform values across each zone; hides within-zone variation; class boundaries can misrepresent data distribution | Showing how a variable varies across named areas or administrative zones |
| Pie chart | Proportions of a total are visually clear; simple to construct; proportional circles allow comparison of totals as well as proportions | Very hard to compare multiple pie charts; small segments are impossible to distinguish; cannot show change over time | Showing the breakdown of a single total into proportional parts at one location |
| Bar chart | Easy comparison between discrete categories; heights make relative sizes obvious; compound versions show sub-categories | Only works for discrete categories; shows totals/means — hides spread; misleading if scale does not start at zero | Comparing values across named, separate categories (sites, land uses, days) |
| Line graph | Trend direction visible immediately; multiple lines allow direct comparison; rate of change shown by slope | Implies continuity between measurement points — risky with small samples; never appropriate for discrete categories | Showing how a value changes over time or continuously along a transect |
| Dispersion diagram | Shows the full spread of data including outliers; median and IQR can be added; reveals variability that mean alone hides | Less intuitive than a bar chart for most audiences; takes longer to draw; harder to interpret quickly | Comparing the spread and distribution of data across multiple sites |
| Kite diagram | Shows abundance of multiple species/features along a transect simultaneously; succession patterns are immediately visible | Only appropriate for transect data; complex to construct; difficult to read if many species overlap significantly | Vegetation or species transect data showing change with distance |
| Flow map / desire lines | Direction and volume of movement immediately visible; spatial origin-destination patterns are clear | Does not show actual routes taken; overlapping lines become confusing in busy areas; line widths must be drawn to exact scale | Showing where pedestrians, traffic, or goods flow from and to |
Practice questions for Fieldwork Presentation and Evaluation Skills
A student is investigating whether pebble size decreases with distance from a cliff. They have 20 paired measurements of distance (metres) and pebble long axis (mm). Which presentation technique is most appropriate?
