Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What are the three broad families of presentation method available for fieldwork data?

    Model answer

    Visual methods such as photographs and field sketches, graphical methods such as bar charts and scatter graphs, and cartographic methods that put the data onto a map.

  2. 2

    What is a located bar chart?

    Model answer

    A bar chart placed on a base map at the point where its data was collected, so the values and their places are seen together.

  3. 3

    Which presentation method suits fieldwork data collected for whole areas rather than points?

    Model answer

    A choropleth map, because it shades each area by its value and shows the pattern across the whole survey area at once.

  4. 4

    What is a flow line map, and what does it show?

    Model answer

    A map on which arrows follow the routes taken by traffic, shoppers or migrants, the width of each arrow being proportional to the number moving along it.

  5. 5

    Which presentation method best shows whether one measurement changes with another, such as velocity against distance downstream?

    Model answer

    A scatter graph with a line of best fit, because it shows the direction and strength of the relationship between the two sets of values.

  6. 6

    Which method best shows how a total is divided into its parts, such as the land uses along a street?

    Model answer

    A pie chart or a divided bar, because each segment is a share of one whole.
