Take Sampling, Ethics and Practical Issues further

The same content, four other ways.

Commonly confused

Pairs that lose marks when they are blurred together.

  • Anonymity vs Confidentiality

    Anonymity: the researcher cannot identify the participant. Confidentiality: the researcher can identify them but will not disclose it.

  • Deception vs Covert research

    Deception: actively misleading participants. Covert research: concealing from a group that it is being studied at all.

  • Sampling frame vs Target population

    Sampling frame: the list from which cases are drawn. Target population: the whole group the findings are meant to apply to.

Questions from this topic

Each one with the model answer underneath.

  1. 1

    Define the target population of a study.

    Model answer

    The whole group about which the researcher wants to draw conclusions.

  2. 2

    What is a sampling frame?

    Model answer

    A list of all the members of the target population from which a sample is drawn.

  3. 3

    Give two examples of lists that can serve as a sampling frame.

    Model answer

    The electoral register and a school's roll of pupils.

  4. 4

    Why must a sampling frame be complete for a random sample to be representative?

    Model answer

    Anyone missing from the list has no chance of selection, so groups omitted from it cannot appear in the sample.

  5. 5

    Give one reason a sampling frame may be out of date.

    Model answer

    People move, die or change status between the list being compiled and the sample being drawn.

  6. 6

    Explain why some target populations have no usable sampling frame.

    Model answer

    Groups defined by hidden or illegal activity, such as drug users, are not recorded on any list, so there is nothing to sample from.
