Sample Data Collection and Graphing questions

  1. Question 1 · Data Collection and Graphing

    During a session, the RBT gives the instruction to clean up the toys and starts a stopwatch immediately. The RBT stops the watch the moment the client picks up the first toy. What is the RBT measuring?

    1. A. Frequency
    2. B. Duration
    3. C. Latency
    4. D. Interresponse time
    Show the answer

    C. Latency

    Latency is the time between an instruction and the start of the response, which is exactly what the stopwatch is timing here. Duration would instead time how long the cleaning itself takes once it starts.

  2. Question 2 · Data Collection and Graphing

    Compared with the actual amount of time a behavior occurs, how do partial interval and whole interval recording tend to differ?

    1. A. Partial interval tends to underestimate it, and whole interval tends to overestimate it
    2. B. Both tend to overestimate it, since one brief instance can score a whole interval
    3. C. Both tend to underestimate it, since behavior is checked only at the end of each interval
    4. D. Partial interval tends to overestimate it, and whole interval tends to underestimate it
    Show the answer

    D. Partial interval tends to overestimate it, and whole interval tends to underestimate it

    Partial interval recording scores an interval if the behavior occurs at any point, so brief behavior fills whole intervals and the total looks larger than it was. Whole interval recording scores an interval only if the behavior lasts all of it, so any break drops the interval and the total looks smaller.

  3. Question 3 · Data Collection and Graphing

    A client's plan scores handwriting from each finished worksheet. A letter counts as correct only if it sits on the line and is closed where it should be. How should the RBT score the worksheet?

    1. A. Check every letter against both criteria and count the letters that meet both
    2. B. Count every letter an adult could read, since readable letters show the skill
    3. C. Rate the whole page as neat or messy based on how it looks overall
    4. D. Count only the letters the client seemed to work hardest on
    Show the answer

    A. Check every letter against both criteria and count the letters that meet both

    Permanent product data are scored against the definition in the plan, so the RBT checks each letter for both stated criteria. Counting any readable letter or judging overall neatness swaps in the RBT's own standard and makes the scores inconsistent from one day to the next.
