Types of Interval Recording
When & Why We Use It
Data & Graphing
Interpreting Interval Data
100

Behavior only needs to happen once during the interval to count.

What is partial-interval recording?

100

This method works best when you can’t watch behavior continuously. 

What is MTS?

100

Interval data is graphed as this.

What is percentage of intervals?

100

When data looks higher or lower than what actually happened.

What is sampling bias?

200

Behavior must occur for the entire interval.

What is whole interval recording?

200

Whole-interval recording is usually used to do this to behavior. 

What is increase behavior?

200

Behavior occurred in 4 out of 10 intervals.

What is 40%?

200

This system may underestimate behavior.

What is whole-interval recording (or MTS)?

300

Behavior is recorded only when the timer sounds. 

What is momentary time sampling (MTS)?

300

Partial-interval recording is usually used to do this to behavior. 

What is decrease behavior?

300

Shorter intervals do this to accuracy. 

What is increase accuracy?

300

We should make decisions based on this instead of one session.

What are patterns across sessions?

400

This system usually makes behavior look higher than it really is.

What is partial-interval recording?

400

We use discontinuous measurement mainly because of this.

What is busy or fast-paced sessions?

400

Longer intervals do this to accuracy. 

What is decrease accuracy?

400

Continuous measurement records this.

What is every occurrence of behavior?
