Key term

Contrast event sampling with time sampling.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What are behavioural categories in observational research?

    Model answer

    Operationally defined, objective descriptions of specific behaviours that observers record during an observation.

  2. 2

    Why must behavioural categories be clearly operationalised?

    Model answer

    So that different observers can reliably identify and record the same behaviours, ensuring consistency between observers.

  3. 3

    Why should behavioural categories be exhaustive?

    Model answer

    So that all possible target behaviours can be categorised, ensuring no relevant behaviour is left unrecorded.

  4. 4

    Define event sampling as an observational technique.

    Model answer

    A technique where the observer records every occurrence of a specified target behaviour during the observation period.

  5. 5

    When is event sampling particularly useful?

    Model answer

    When the target behaviour occurs relatively infrequently.

  6. 6

    What is a limitation of using event sampling?

    Model answer

    It may miss behaviours that occur very frequently or continuously, as each instance must be recorded separately.
