Types of Interval Recording
Behavior only needs to happen once during the interval to count.
What is partial-interval recording?
This method works best when you can’t watch behavior continuously.
What is MTS?
Interval data is graphed as this.
What is percentage of intervals?
When data looks higher or lower than what actually happened.
What is sampling bias?
Behavior must occur for the entire interval.
What is whole interval recording?
Whole-interval recording is usually used to do this to behavior.
What is increase behavior?
Behavior occurred in 4 out of 10 intervals.
What is 40%?
This system may underestimate behavior.
What is whole-interval recording (or MTS)?
Behavior is recorded only when the timer sounds.
What is momentary time sampling (MTS)?
Partial-interval recording is usually used to do this to behavior.
What is decrease behavior?
Shorter intervals do this to accuracy.
What is increase accuracy?
We should make decisions based on this instead of one session.
What are patterns across sessions?
This system usually makes behavior look higher than it really is.
What is partial-interval recording?
We use discontinuous measurement mainly because of this.
What is busy or fast-paced sessions?
Longer intervals do this to accuracy.
What is decrease accuracy?
Continuous measurement records this.
What is every occurrence of behavior?
