Mathematical Requirements for Research Methods

Identifying levels of measurement in quantitative and qualitative data

  • 2 things to know
  • Component 01

Overview

Recall questions on what is lost converting interval to ordinal data, identifying the level of measurement in example studies, the level of qualitative data, weaknesses of quantitative and qualitative data, and converting transcripts into numbers.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is lost when interval data is converted into ordinal data for a test?

    Model answer

    The actual size of the differences between scores, since only their rank order is retained.

  2. 2

    A researcher records whether each participant is left-handed or right-handed. State the level of measurement.

    Model answer

    It is nominal, because participants are simply allocated to named categories.

  3. 3

    Runners are recorded as finishing first, second and third. State the level of measurement and justify it.

    Model answer

    It is ordinal, because the positions are ranked but the time gaps between them are unequal and unknown.

  4. 4

    A study records the number of words each participant recalled. Is this quantitative or qualitative data, and at what level of measurement?

    Model answer

    It is quantitative data at the interval level, because the scores are numerical and counted in equal units.

  5. 5

    What level of measurement does qualitative data have before it is analysed?

    Model answer

    It has none, because it is not numerical, so it acquires a level of measurement only once it is coded into categories and counted.

  6. 6

    Give one weakness of quantitative data.

    Model answer

    It reduces experience to numbers, so it can establish that a difference exists without showing why participants behaved as they did.
