C07 Design and Implement Sampling Procedures Part 1 Flashcards
The partial interval method overestimates the actual occurrence of behavior because
Behavior may occur during a small part of the interval but the entire interval is scored
Whole-interval recording is often used when measuring
Behaviors that occur at such a high rate that it is difficult to distinguish one response from the next
When using momentary time sampling
Use intervals that are either variable or fixed.
With momentary time sampling, you record the behavior if it occurs
At the end of the interval
Using a momentary time sampling procedure, it is necessary to observe
Very briefly at the end of the interval
The term TIME SAMPLING refers to a variety of methods for observing and recording
A sample of behavior during intervals or at specified moments in time
The whole interval method underestimates the actual duration of behavior
Because rarely do occurrences of the behavior occur throughout the entire interval
With partial interval recording, you record the behavior if it occurs
At any point in the interval
When using whole-interval recording, your data are more likely to underestimate the actual rate or duration of the target behavior when the observation period is divided into
Longer intervals
Whole interval recording is often used when measuring
Continuous behavior
With whole interval recording, you record the behavior if it occurs
Throughout the entire interval
When using partial interval recording, your data are more likely to overestimate the actual rate or duration of the target behavior when measuring
Low-frequency behavior
When using a partial interval recording procedure, indicate an occurrence only if the behavior
Occurs at any time in the interval
Time sampling data
More closely estimate the amount of behavior when intervals are short and observations are conducted frequently
