Measurement is the first domain of the RBT Task List and roughly 16 percent of your scored questions. This quiz drills the distinctions the exam actually tests: frequency versus rate, duration versus latency, partial versus whole interval, and when each procedure fits which behavior.

Answer each question, read the explanation even when you are right, and note which distinctions cost you points. The matching study guide section below covers the full domain in prose.

Measurement Domain Quiz (10 questions, untimed)

What the Measurement domain covers

The exam expects you to prepare for data collection, use continuous procedures (frequency, rate, duration, latency, inter-response time), use discontinuous procedures (partial interval, whole interval, momentary time sampling), record permanent product data, and enter data and update graphs.

The trap in this domain is that every procedure sounds reasonable for every behavior until you think about what each one distorts. Partial interval inflates, whole interval deflates, momentary time sampling misses everything between checks, and rate is the only honest way to compare sessions of different lengths. Questions are built around exactly those trade-offs.

Frequently asked questions

How many measurement questions are on the RBT exam?
The published outline allocates 12 of the 75 scored questions to Measurement, about 16 percent. With pilot items you may see a few more that do not count.
What is the difference between frequency and rate?
Frequency is a raw count of occurrences. Rate is that count divided by observation time, like 3 per hour, which is what makes different session lengths comparable.
Which interval method overestimates behavior?
Partial interval recording, because a single second of behavior scores the whole interval. Whole interval recording underestimates for the mirror-image reason.
