BCAT Data Collection & Analysis 3

Question 1

When graphing behavior data, which axis should always represent the behavior being measured?

Accepted Answer

The y-axis (vertical)

Answer

In behavior analysis graphs, the y-axis (ordinate) represents the dependent variable, which is the behavior being measured.

Question 2

A client's data shows a flat, stable trend for three consecutive weeks despite an active intervention. This pattern is BEST described as:

Accepted Answer

A zero-celerating or horizontal trend

Answer

A flat or zero-celerating trend means the behavior is neither increasing nor decreasing, which may prompt the BCBA to modify the intervention.

Question 3

Which of the following BEST describes latency recording?

Accepted Answer

Recording the time elapsed from a stimulus to the start of a behavior

Answer

Latency recording measures the elapsed time from the presentation of a discriminative stimulus (SD) to the initiation of the target response.

Question 4

A technician is recording data using whole interval recording. The behavior must occur:

Accepted Answer

Throughout the entire interval to be scored

Answer

Whole interval recording only scores an interval if the behavior is present for the entire duration of that interval, which tends to underestimate behavior occurrence.

Question 5

A phase change line on a behavior graph indicates:

Accepted Answer

A change in the independent variable or treatment condition

Answer

A vertical phase change line separates different experimental conditions or intervention changes on a behavior graph.
