What is an example of interval recording?
Whole interval recording means that the observer is interested in behavior that occurs during the entire interval. Examples of ongoing behaviors that can be observed using whole interval recording include writing, walking, reading, or working on a given assignment.
What is partial interval recording used for?
Partial interval recording can be used to measure behaviors that happen so quickly that it is hard to catch (the behavior itself does not last for a long time). You will need a timing instrument such as a wall clock, wristwatch, or stopwatch in order to keep track of the time intervals.
What is the difference between partial interval recording and whole interval recording?
-Whole-interval recording yields data on the total duration of the behavior. -Partial-interval recording yields data on the proportion of the observations period that the behavior occurred.
How long should intervals be for partial interval recording?
The shorter the interval, the more accurate the data will be, but the more work that will be required by the observer. Interval length should be set to approximate baseline rates of behavior (if we think behavior tends to occur every 10 minutes then 5-10 minute intervals makes sense).
How do you record partial intervals when recording?
In partial interval recording, the observer marks down whether a behavior occurs any time during the interval by placing an "X" for occurrence and a "O" for no nonoccurrence. A student may engage in a behavior multiple times during the interval or only once for an "X" to be documented.
