Continuous Measurement
Measuring each and every instance of behavior within the
... [Show More] entire observation
period.
What are the 5 types of continuous measurement?
Frequency, Rate, Duration, Inter Rate Response (IRR), and Latency.
Frequency
A simple count of the instances of a behavior, represented by a tally.
Example; how many times did John hit another student? You would tally every
time John hit another student and present the count as a number. John hit
another student five times.
Rate
A frequency count with a time element. This type of continuous measurement is
an important measurement when looking at behaviors which are frequent and
short, like hitting, raising hands, flapping hands, disrupting another student,
yelling.
Example; if you are measuring how many times John hit another student, you
would report this as John hits at the rate of five times per hour.
Duration
How long a Behavior occurs. To take this type of data you start a stopwatch when
the behavior begins and end the stopwatch when the behavior stops. This data is
often reported as an average over time, and is for behaviors that are long lasting
like tantrums, social play, how long it takes a child to get dressed.
Inter Rate Response (IRT)
This is the observed time between responses. To take this type of data you start
the stopwatch when the behavior ends and stop the stopwatch when the
behavior begins again. This type of data is typically reported as an average.
Example; The time between doing math problems, the time between prosocial
behaviors.
Latency
This is the time from prompt to the start of the behavior. To take this type of data
start the stopwatch when the prompt is given and stop the stopwatch when the
behavior starts. You might want to take this type of data when there is a delay
between the prompts and when the behavior occurs.
Example; The time from a prompt to get dressed to a person getting dressed, the
time from the instruction to begin a math problem to the response.
Discontinuous Measurement
These measurement procedures are classified as samples of the target behavior,
but they do not measure every instance of a behavior within the entire
observation period. These types of measurement procedures are used when it is
too time-consuming to take continuous measurement data.
What are the 3 types of Discontinuous Measurement?
Partial interval, whole interval, and momentary time sampling.
Partial Interval
A type of discontinuous measurement that records the presence or absence of a
behavior during a brief interval of time. Intervals are marked as positive if the
target behavior occurred at any time during the interval, and negative if the
target behavior did not occur during the entire interval.
Example; take an interval of 30 seconds and look for hand flapping behavior. You
would mark a positive if the hand flapping behavior occurred at any point during
the 30 second intervals, and a negative if it did not.
Whole interval
A discontinuous measurement procedure that records the presence or absence of
a behavior during the whole interval. Intervals are marked as a positive if the
target behavior occurred during the entire interval, and a negative if the target
behavior stopped at any time during the interval.
Example; if you are doing a 30 second intervals and measuring hand flapping
behavior, you would mark it positive if the hand flapping behavior occurred
during the entire 30 seconds, or negative if the hand flapping behavior stopped at
any point in time during those 30 seconds.
