Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a conclusion in a piece of geographical work?

    Model answer

    A statement that answers the original question directly, resting on the data that was collected.

  2. 2

    What makes a conclusion an informed one?

    Model answer

    It follows the figures actually found and quotes them, rather than the result that was expected beforehand.

  3. 3

    Why should figures be quoted in a conclusion?

    Model answer

    They show that the conclusion came from the evidence and let a reader judge how strong it is.

  4. 4

    What should be done with readings that do not fit the general result?

    Model answer

    They should be pointed out as anomalies and a reason for them suggested, never quietly dropped.

  5. 5

    Why is it wrong to say one thing causes another simply because two sets of figures rise together?

    Model answer

    Figures rising together show only that the two vary in step, and some other factor may be driving both.

  6. 6

    How is the strength of a conclusion judged?

    Model answer

    By how much data supports it, how consistent the readings are, and whether anything measured contradicts it.
