Flashcards in Measuring Dimensions Deck (20):
What are the 4 dimensions of behaviour that can be measured?
Give definition and formula for calculating frequency
Number of times behaviour occurred. Converted into %
(Number of behaviours) x 100%
(Number of opportunities)
Give definition and formula for calculating rate
Number of times behaviour occurred during given period e.g.
Number of behaviours = rate/min
Number of observations
Give definition and formula for calculating duration
How long behaviour lasts. Calculate %
Give definition of latency
How long it takes for behaviour to start
When is using latency as a measure useful?
When reinforcing the effectiveness of activities
If behaviours have a clear onset and offset you can usually get a precise measure of them using (dimensions)
Duration, frequency, latency
When it is difficult to get precise measurements of behaviour (due to a very high occurrence or no clear onset), ____ ____ should be used
The first step in time sampling is to
Divide your observation period into intervals
Once observation period has been divided into intervals,
You mark whether that behaviour occurred in each interval
What is the calculation for time sampling? What is the data then presented as?
Number of intervals marked x 100%
Number of intervals in total
Presented as percentage of intervals
Name and define the 3 types of time sampling
1 whole interval - interval is marked if behaviour occurred throughout the entire interval
2 partial interval - interval marked if behaviour occurred at any point
3 momentary - behaviour marked if it occurs at end of interval (usually)
When should you use whole interval recording?
When goal is to increase behaviour
When should you use partial interval recording?
When goal is to decrease behaviour
When should you use momentary time sampling?
When continuous observation throughout the observation is not feasible.
Determining whether behaviour has occurred by measuring the outcome of behaviour is known as
Permanent product recoding
When should permanent product recording be used?
When observation is not possible and the behaviour has a visible, permanent outcome
What does real time recording refer to?
Recording the exact time of each onset/offset of behaviour, so frequency and duration are recorded at the same time
When is rate used instead of frequency?
When the duration of observation periods are of varying length
