Observational Designs Flashcards
What are the three main observational designs?
- Behavioural categories
- Time sampling
- Event sampling
What is a behavioural categories?
The target behaviour to be observed should be broken up into a set of observable categories
What is behavioural categories similar to?
Operationalisation
What are the limitations of behavioural catergories?
- Difficult to make clear and unambiguous
- Dustin categories = behaviours go unrecorded
What is time sampling?
observations are made at intervals e.g every 15 seconds
Strength of time sampling:
Reduce number of observations = structured and systematic
Limitation of time sampling:
Unrepresentative = may miss important details out of time-scale
What is event sampling?
A target behaviour or event is recorded every time it occurs
Strengths of event sampling:
May require infrequent behaviours
Limitations of event samplings:
Complex behaviours oversimplified = important details may go unrecorded
