Scientific processes (observational design) Flashcards
Time sampling
This is where an observer records behaviour at prescribed intervals eg. every 10 seconds
Limitation of time sampling
Not every behaviour of relevance to the investigation will be counted if it occurs in between the time frames allocated
Event sampling
This is where an observer records the number of times that the target behaviour occurs eg. using tally
Limitation of event sampling
There is a possibility that some behaviours could be missed if there is too much happening at the same time
Strength of time sampling
Time sampling methods allow for better use of time since fewer observations are made
Strength of event sampling
Every behaviour of interest to the researcher will be counted from the beginning through to the end of the observation
