observational design Flashcards
What are the issues in the design of observation?
What the researcher would have to plan when doing an observational study
What is a structured observation?
Involves pre-determined behaviours and sampling methods which are appropriate for larger observations.
What are the strengths of a structured observation?
- easier recording of data and more systematic
- produces quantitative data which is easier to analyse
What are the weaknesses of a structured observation
- important behaviours may be missed
What is an unstructured observation?
The researcher writes down everything that they see which produces rich data. This would be appropriate for small observations.
What are the strengths of an unstructured observation?
More detailed and rich data
What are the weaknesses of an unstructured observation?
- Produce qualitative data which is harder to analyse and record
- Greater risk of researcher bias as there are no behavioural categories
What are behavioural categories?
Breaking down a target behaviour into components that are observable and measurable.
What are the strengths of behavioural categories?
- Make data collection more objective and structured
What are the weaknesses of behavioural categories?
- Can be problematic if behaviour categories are not clear
- All categories of the target behaviour should be included and if they aren’t this can result in a dustbin category
What are the sampling methods?
- Event
- Time
- Continuous
What is event sampling?
The target behaviour is established and then it is recorded every time it occurs.
What are the strengths of event sampling?
- Useful when behaviour
What is event sampling?
When targe behaviour is established and then it is recorded every time it occurs
What are the strengths of event sampling?
It is useful when behaviour happens infrequently and could be missed when using time sampling
