Data Collection and Graphing Quiz (Difficult)

Question 1 of 15

An RBT is tracking a client's 'manding' (requesting) during a 4-hour session. The RBT records exactly 20 mands. The supervisor asks for the 'rate' per hour. What should the RBT report?

Rate is frequency divided by time. 20 mands / 4 hours = 5 mands per hour.

Question 2 of 15

A client engages in a tantrum that begins at 2:00 PM and ends at 2:12 PM. What dimension of behavior is the RBT measuring?

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

Question 3 of 15

An RBT is recording how long it takes for a student to start their worksheet after the teacher says, 'Start your work.' The student waits for 45 seconds before picking up their pencil. What is this measurement?

Latency is the time between the delivery of a stimulus (instruction) and the initiation of a response.

Question 4 of 15

A supervisor asks an RBT to use 'Momentary Time Sampling' with 1-minute intervals to track 'on-task' behavior. When should the RBT record data?

Momentary time sampling involves recording whether the behavior is occurring at the very end of a specific interval.

Question 5 of 15

An RBT is using a 30-second interval timer. If the client engages in hand-flapping at *any point* during the 30 seconds, the RBT marks the interval as an occurrence. What measurement is this?

Partial interval recording marks an occurrence if the behavior happens at any point during the interval.

Question 6 of 15

A student completes 15 math problems on a worksheet. The RBT grades the worksheet after the student has left the room. What type of measurement is this?

Permanent product recording measures the tangible outcome or result of a behavior rather than the behavior itself.

Question 7 of 15

An RBT is asked to record the time between the end of one instance of 'shouting' and the beginning of the next instance of 'shouting.' What measurement is this?

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

Question 8 of 15

A supervisor asks the RBT to use 'Whole Interval Recording' for a 1-minute interval to track 'sitting in chair.' The client sits for 58 seconds but stands up for the last 2 seconds. How should the RBT record this interval?

In whole interval recording, the behavior must persist for the entire duration of the interval to be marked as an occurrence.

Question 9 of 15

When looking at a line graph, the RBT notices that the data points are moving steadily downward over several weeks. What does this describe?

Trend refers to the overall direction in which the data path is moving.

Question 10 of 15

An RBT and a supervisor are both recording the frequency of a client's hitting to ensure their data matches. What is this process called?

IOA is the degree to which two or more independent observers report the same observed values after measuring the same events.

Question 11 of 15

On a standard line graph, the vertical axis (y-axis) usually represents which of the following?

The y-axis represents the quantitative dimension of the behavior being measured.

Question 12 of 15

A client's data points for aggression are scattered all over the graph, with no clear pattern (e.g., 0, 15, 2, 20). How should the RBT describe this data?

Variability refers to the extent to which multiple measures of a behavior differ from each other.

Question 13 of 15

A supervisor draws a vertical dashed line on a graph between 'Session 5' and 'Session 6.' What does this line signify?

Vertical phase change lines are used to show when a change in the environment or intervention occurred.

Question 14 of 15

An RBT is recording 'Trials to Criterion' for a puzzle-solving task. What are they measuring?

Trials to criterion measures the amount of practice required to learn a skill.

Question 15 of 15

A supervisor asks the RBT to calculate the 'Percentage of Occurrence' for a DTT program. The client got 8 trials correct out of 10 total trials. What is the percentage?

Percentage is calculated by dividing the number of correct responses (8) by the total number of opportunities (10) and multiplying by 100.
