Momentary time sampling is most likely to produce accurate estimates when behavior occurs:
Answer: Continuously and at a steady state throughout the interval
Momentary time sampling is most accurate for behaviors that occur at a relatively steady, continuous rate across the observation period.
Which of the following is an advantage of using permanent product recording?
Answer: Data collection does not require the observer to be present during behavior
Permanent product recording measures the tangible outcomes of behavior after it occurs, so the observer need not watch the behavior happen.
A practitioner records data only at the end of each 10-minute interval to note whether the target behavior is occurring at that exact moment. This is:
Answer: Momentary time sampling
Momentary time sampling records whether the behavior is occurring only at the precise moment the interval ends.
When a data path shows high variability across sessions, the analyst should:
Answer: Examine potential sources of measurement error or inconsistent treatment implementation
High variability often signals inconsistent procedures, measurement error, or environmental variables that should be investigated before changing the intervention.
Which level of measurement allows for calculation of meaningful ratios, has a true zero, and supports all arithmetic operations?
Answer: Ratio
Ratio-level measurement has a true zero point, meaning zero represents the complete absence of the property being measured.
A behavior analyst graphs cumulative response records. A steeper slope on this graph indicates:
Answer: A higher rate of responding
In a cumulative record, a steeper slope reflects more responses occurring in a shorter time, indicating a higher response rate.
Which of the following scenarios would most warrant using duration recording rather than frequency recording?
Answer: A student engages in prolonged out-of-seat behavior throughout the school day
Duration recording is most appropriate for continuous behaviors where how long the behavior lasts is more clinically relevant than how many times it occurs.
