  1. A BCBA notices a client's data path has been flat for 3 consecutive weeks despite an intervention. According to data-based decision rules, what is the most appropriate action?

    Answer: Modify or change the intervention

    Three consecutive data points showing no improvement (a flat trend) is a common decision rule indicating the intervention should be modified or changed.

  2. Which graphing convention is used in ABA to visually separate baseline and intervention phases?

    Answer: A vertical phase change line

    Vertical phase change lines are the standard ABA convention to separate and clearly distinguish different experimental phases on a graph.

  3. When calculating the mean of a data set for a phase, which measure is being computed?

    Answer: The arithmetic average of all data points

    The mean is the arithmetic average, calculated by summing all values and dividing by the number of data points.

  4. A practitioner plots data on a standard celeration chart. What does 'celeration' specifically measure?

    Answer: The rate of change in frequency over time

    Celeration is the rate of change (acceleration or deceleration) in response frequency across time, which is the primary metric of the Standard Celeration Chart.

  5. An ABA team is using a criterion-referenced decision rule. The goal is 80% accuracy for 3 consecutive sessions. The client scores 82%, 79%, 84%. Has the criterion been met?

    Answer: No, because the second session fell below 80%

    A consecutive sessions rule requires all specified sessions to meet criterion; one session below 80% breaks the consecutive requirement.

  6. Which data display method is best suited for comparing a client's performance across multiple different skill domains simultaneously?

    Answer: A bar graph

    Bar graphs allow side-by-side visual comparison of performance levels across multiple distinct categories or skill domains.

  7. A behavior analyst uses the split-middle method to draw a trend line. What is the first step in this procedure?

    Answer: Divide the phase data into two equal halves

    The split-middle method begins by dividing the data set into two equal halves before finding the median of each half to establish the trend line.
