Common Mistakes That Cost Marks

⚠️ Common Mistakes That Cost Marks

Misconception 1: "I should join the dots on a scatter graph"

Joining dots on a scatter graph is one of the most common errors in fieldwork presentations. A scatter graph shows whether a correlation exists between two variables — the "scatter" of points is the information. Joining the dots turns it into a jagged line graph, which implies a sequential time-series relationship between the measurements when none exists. Each point is independent. The correct addition to a scatter graph is a smooth line of best fit, not point-to-point connections.

Misconception 2: "A pie chart is good for showing change over time"

Pie charts show how a single total is divided into proportional parts at one moment. They cannot show change over time because they have no time axis. A student who draws a "pie chart of traffic counts across Monday to Sunday" has drawn the wrong technique entirely — a line graph (with days on the x-axis and count on the y-axis) is the correct choice because it shows how the value changes as time progresses.

Misconception 3: "Describing the pattern is the same as analysing it"

Description says what the data shows. Analysis explains why. "Pebble size decreases from Site 1 to Site 5" is a description. "Pebble size decreases from 42 mm at Site 1 to 11 mm at Site 5, consistent with the process of attrition during longshore transport, which progressively rounds and reduces pebble dimensions" is analysis. The examiner marks analysis, not description. A response that is entirely descriptive will never exceed Level 1 on a 6-mark or 8-mark question.

Misconception 4: "I do not need to write units on my axes"

Axes without units are technically incomplete and will lose marks in any assessed fieldwork piece. "Pebble size" on the y-axis tells the examiner nothing about whether you measured in millimetres, centimetres, or some other unit. "Pebble size (mm)" or "Pebble b-axis diameter (mm)" is correct. Every numerical axis must have both a variable name and a unit.

Misconception 5: "Photo annotations just need to label what I can see"

Labelling visible features (writing "rock" next to a rock, "river" next to a river) is description, not annotation in the GCSE sense. A geographical annotation must add meaning that is not immediately visible in the photograph itself. It should connect what you can see to a geographical process, theory, or pattern: "Angular, poorly sorted sediment — indicates this is close to the source and has undergone limited transport compared to the well-rounded sediment photographed downstream at Site 4."
