  1. Question 1Skills & concepts

    Validating qualitative findings by checking them with the original participants is called

    • amember checking
    • bpeer debriefing
    • ctriangulation
    • dcoding
  2. Question 2Recall

    Closed-ended questions in a questionnaire are those that

    • arequire specific options for answers, such as yes/no, multiple choice or a rating scale
    • ballow respondents to answer freely in their own words
    • ccan only be asked during a face-to-face interview
    • dhave no correct answer and are never analysed
  3. Question 3Skills & concepts

    In a box plot, the "whiskers" extend from

    • athe lower quartile down to the minimum value, and the upper quartile up to the maximum value
    • bthe median out to both quartiles
    • cthe minimum to the maximum, passing straight through the box
    • dthe mean out to the median in both directions
  4. Question 4Recall

    The simplest measure of dispersion, found by subtracting the lowest value from the highest, is

    • athe range
    • bthe mean absolute deviation
    • cthe interquartile range
    • dthe standard deviation
  5. Question 5Skills & concepts

    When organising a questionnaire, the recommended approach to question order is to

    • abegin with the simple questions and keep the more challenging ones for later
    • bbegin with the most difficult questions while respondents are fresh
    • cplace questions in a completely random order
    • dask only demographic questions and nothing else
