Answer 3

trend
variability
level

Question 8

Which of the following phases of an A-B-A-B design would be compared in the protocol described by Wolfe et al., 2019?

All of these answers are correct.

first baseline to first treatment

second baseline to second treatment

similar phases (treatments to treatments and baselines to baselines)

Answer 8

All of these are correct

Question 9

Which of the following questions from the ABAB Protocol described by Wolfe et al., 2019 would correspond to consistency?

Are the data patterns of the first and second baseline phases similar in level, trend, or variability?

None of these answers is correct.

Do less than 30% of the data points in the first treatment phase overlap with the data point s in the first baseline phase?

Is there an immediate change from the last 3-5 data points in the first baseline to the first 3-5 data points in the first treatment?

Answer 9

Are the data patterns of the first and second baseline phases similar in level, trend, or variability?

Question 10

Use the ABAB Protocol from Wolfe et al., 2019 to determine which of the following statements is true regarding the data depicted in the following graph.

graph-2.png

The data patterns in the first and second treatment phases are not similar in variability.

The data patterns in the first and second baseline phases are not similar in level.

There are at least 3 data points in the first baseline phase but the future pattern of behavior cannot be predicted.

There is an immediate change from the last 3-5 data points in the first treatment phase to the first 3-5 data points in the second baseline phase.

Answer 10

There is an immediate change from the last 3-5 data points in the first treatment phase to the first 3-5 data points in the second baseline phase.

Question 11

Use the Multiple-Baseline Protocol from Wolfe et al., 2019 to determine which of the following statements is NOT true regarding the data depicted in the following graph.

graph2.png

Data patterns of treatment for tier 1 and tier 3 are different in level, trend, and variability.

Less than 30% of the treatment data points overlap with the baseline data points for tier 3.

There is an immediate change from the last 3-5 data points in baseline to the first 3-5 data points in treatment for tier 2.

There are at least 3 data points in tier 1 and you can predict the future pattern of the behavior.

Answer 11

Data patterns of treatment for tier 1 and tier 3 are different in level, trend, and variability.

Question 12

In order to assess the
_____ of the visual analysis protocol, decisions produced by the protocol were compared to decisions made by expert visual analysts.

Answer 12

validity

Question 13

Which of the following statements is true regarding the protocols for visual analysis of single-case research data described in this study?

All of these answers are correct.

While reliability improved, the correspondence of the protocol with expert visual analysis was low.

While the protocols improved reliability, the social validity of the protocols was not investigated.

The protocols improved reliability among visual analysts from fair to excellent.

Answer 13

The protocols improved reliability among visual analysts from fair to excellent.
