Question 1

Which of the following graphs would BEST display cumulative frequency data over time?

Accepted Answer

Cumulative record

Answer

A cumulative record plots the running total of responses over time, never decreasing, and its slope reflects response rate.

Question 2

A supervisor wants to evaluate whether a skill trained in one setting transfers to a novel setting. This evaluation is assessing:

Accepted Answer

Stimulus generalization

Answer

Stimulus generalization occurs when a behavior trained under one set of stimuli appears under different but similar stimuli or settings.

Question 3

A researcher reports that an intervention produced a statistically significant effect with p < 0.05. What additional information is most important for evaluating the practical significance?

Accepted Answer

Effect size

Answer

Effect size quantifies the magnitude of the treatment effect, providing practical significance beyond what a p-value alone can indicate.

Question 4

During a study, observers know when conditions change and begin recording differently as a result. This threat to internal validity is called:

Accepted Answer

Instrumentation

Answer

Instrumentation refers to changes in measurement procedures or instruments over time that can confound results, including observer behavior changes linked to condition awareness.

Question 5

A supervisor reviews a line graph where data points in the treatment phase are consistently below the projected trend line from baseline. This visual analysis indicates:

Accepted Answer

A therapeutic treatment effect

Answer

When treatment data fall below a projected worsening baseline trend (for a behavior targeted for decrease), it indicates a therapeutic effect.
