observational design Flashcards
how are unstructured observations done?
all relevant behaviour is recorded and no system of recording
behaviour is used.
what is the problem with unstructured observations?
there could be too much info to record. some behaviour recorded might not be relevant/important
when may a researcher use unstructured observation ?
where research has not been carried out before, as a kind of ‘pilot study’ to see what behaviours might be recorded using a structured system.
are structured or unstructured observations better for objectivity?
structured
how are structured observations done?
various systems are used to record behaviour
what are the two main ways to structure observation?
- behavioural categories
- sampling procedures
how is behaviour operationalised?
through behavioural categories. this involves breaking the target behaviour (e.g. aggression) into components that can be observed and measured (e.g. hitting, kicking).
what 3 things should behavioural categories be?
-objective
-cover all possible component behaviours
-be mutually exclusive(not overlap)
when is continuous observation not possible?
when there is too much data to record
what are the two types of sampling observations
event sampling
time sampling
what is event sampling?
it is where an observer records the number of times a certain behaviour occurs.
what is time sampling?
where an observer records behaviour at prescribed intervals. For example, every 10 seconds.
what is the disadvantage of only one observer?
they could be biased or miss data
how is reliability improved in observations?
2 or more observers should be used
what is inter-observer reliability?
refers to the extent to which two or more observers are observing and recording behaviour in the same way.
