Question 1 of 15

An RBT is tracking how many times a student raises their hand during a 30-minute math block. The RBT records a tally each time the behavior occurs. Which measurement is being used?

Frequency is a simple count of how many times a behavior occurs within a specific period.

Question 2 of 15

A supervisor asks an RBT to measure how long a client's tantrum lasts from the first scream until the client has been calm for 30 seconds. What is the most appropriate measurement?

Duration measures the total amount of time from the onset to the offset of a behavior.

Question 3 of 15

An RBT is recording the time it takes for a child to sit down after the RBT says, 'Sit in your chair.' The RBT starts the timer at the end of the instruction and stops it when the child's bottom touches the seat.

Latency is the elapsed time between the onset of a stimulus and the initiation of a response.

Question 4 of 15

A teacher wants to know the average time between a student's instances of shouting out in class. The RBT records the time from the end of one shout to the start of the next shout. What is this?

IRT measures the time that elapses between two consecutive instances of the same response class.

Question 5 of 15

During a 1-hour session, an RBT marks a '+' if the client engages in hand-flapping at any point during a 10-second interval. What type of discontinuous measurement is this?

Partial interval recording tracks if the behavior occurred at any point during the interval.

Question 6 of 15

An RBT is observing a client 'staying on task.' The RBT only records a '+' if the client is working for the entire duration of a 30-second interval. This is known as:

Whole interval recording requires the behavior to occur throughout the entire interval.

Question 7 of 15

A supervisor sets a timer to beep every 2 minutes. When the beep sounds, the RBT looks up and records whether the client is playing with toys at that exact moment. What is this called?

Momentary time sampling records the presence or absence of a behavior at the very end of an interval.

Question 8 of 15

An RBT is asked to count how many math problems a student finishes during a 10-minute work session. The RBT then divides the total count by 10. What is the resulting measurement?

Rate is frequency per unit of time (e.g., problems per minute).

Question 9 of 15

An RBT evaluates a student's spelling test and marks the number of words spelled correctly. The student is not present during the grading. What measurement is this?

Permanent product recording measures the durable, tangible outcome of a behavior.

Question 10 of 15

An RBT is plotting data on a line graph. The vertical (y-axis) of the graph is most commonly used to represent which of the following?

In ABA, the y-axis (ordinate) represents the quantitative dimension of the behavior being measured.

Question 11 of 15

While reviewing a graph, the RBT notices that the data points for a client's aggression are highly variable, jumping from 0 to 20 instances across three days. This describes the data's:

Variability refers to the extent to which data points differ from each other or the mean.

Question 12 of 15

An RBT looks at a graph and sees that the data points are consistently getting higher over the last two weeks. This upward movement is called the:

Trend is the overall direction in which the data path is moving (upward, downward, or zero).

Question 13 of 15

After a phase change line is drawn on a graph, the RBT calculates the average value of the data points in the new condition. This average is known as the:

Level is the value on the vertical axis around which a series of data points converge.

Question 14 of 15

A supervisor asks an RBT to calculate the 'Trials to Criterion' for a puzzle-solving task. What is the RBT measuring?

Trials to criterion is the number of response opportunities needed to reach a predetermined level of performance.

Question 15 of 15

When recording 'Percent of Occurrence,' an RBT takes the number of correct responses and divides it by what?

Percentage is calculated by dividing the number of occurrences by the total number of opportunities and multiplying by 100.
