Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is primary data?

    Model answer

    Data that you collect yourself at first hand, in the field, for your own enquiry.

  2. 2

    What is secondary data?

    Model answer

    Data that somebody else has already collected and published, which you then use in your enquiry.

  3. 3

    What is the main advantage of primary data over secondary data?

    Model answer

    It is gathered exactly where, when and how your question needs it, so it is up to date and you know how it was obtained.

  4. 4

    What is the main drawback of primary data?

    Model answer

    It takes time, effort and equipment to collect, so only a small amount can be gathered from a small area.

  5. 5

    Which kinds of physical data could be measured in the field?

    Model answer

    Channel width, depth and velocity, beach gradient, pebble size and roundness, soil moisture, air temperature and wind speed.

  6. 6

    Which counts and surveys would count as human data in an enquiry?

    Model answer

    Pedestrian and traffic counts, questionnaire responses, land use, environmental quality scores, and the types of shop and how many are vacant.
