CBC Data Collection & Measurement Flashcards

What is the primary advantage of using momentary time sampling over whole interval recording?

Answer: It is less affected by observer fatigue during long observation periods

Momentary time sampling only requires observing the client at the end of each interval, making it more practical for lengthy sessions.

Which of the following best defines 'celeration' in the context of Standard Celeration Chart data analysis?

Answer: The rate of change in behavior frequency over time

Celeration describes how quickly behavior frequency is accelerating or decelerating across time on a Standard Celeration Chart.

A behavior consultant notices high variability in baseline data. What is the recommended decision before implementing an intervention?

Answer: Continue baseline until a stable trend is established

A stable baseline is required to establish a valid comparison point; high variability makes it difficult to detect treatment effects.

Inter-response time (IRT) is best used to measure which behavioral characteristic?

Answer: The time between consecutive responses

IRT captures the elapsed time between the end of one response and the start of the next, useful for spacing or fluency goals.

Which type of IOA is most appropriate when a behavior has a very low rate of occurrence?

Answer: Occurrence-only IOA

Occurrence-only IOA focuses agreement calculations on intervals where at least one observer recorded the behavior, preventing inflated agreement due to shared non-occurrences.

A consultant creates a graph where the y-axis displays behavior rate per minute. This is an example of which type of display?

Answer: Equal-interval line graph

An equal-interval line graph plots behavior rate or frequency on a standard arithmetic y-axis across sessions or time.
