research methods: observational design Flashcards
What is observation design?
The choice of behaviours to record and how they are measured
What are behavioural categories?
When a target behaviour is broken down into components that are observable and measurable
What are the components of behavioural categories?
- Operationalisation: breaking the behaviour being studied into a set of components
- Be objective: no inferences about the behaviour, just simply recording
- be mutually exclusive: no overlapping
What is time sampling?
The researcher records behaviour of an individual or a group in a fixed time frame
What are advantages of time sampling?
- effective in reducing the number of observations that have to be made
- more flexibility to be able to record unexpected types of behaviour
What is a disadvantage of time sampling?
Behaviour presented might be unrepresentative of the observation as a whole as it does not look at every single behaviour
What is event sampling?
A target behaviour is established and a researcher records this event every time it happens
What is an advantage of event samplng?
Useful when the target behaviour occurs infrequently which could be missed if time sampling is used
What is a disadvantage of event sampling?
If the specified event is too complex, the observer may overlook important details not on the list of behavioural categories
What are the advantages of structured observations?
- the recording of data is easier and more systematic
-the data produced is likely to be quantitative which makes the analysis and comparisons easier
What is an advantage of unstructured observations?
Richer, more in-depth data from qualitative results
What are the disadvantages of using unstructured observations?
- greater risk of observer bias
- researchers may only record behaviours that ‘catch their eye’
- qualitative data may be much harder to record and analyse
How can you assess observational reliability?
Inter-observer reliability
What is inter-observer reliability?
When two researchers carry out observations independently and compare the data to check for consistency i.e. reliability
What are the steps of carrying out inter-observer reliability?
1) Observers should conduct observations in teams of at least two
2) Observers look for the same behaviours by watching the same event but reversing the data independently
3) The data collected by the two observers is correlated to assess reliability
4) The correlation coefficient should be +0.80
