Question 1

In a single-system design, the baseline period in which the client is being measured before treatment begins is referred to as the treatment phase with the label A.

Accepted Answer

In a single-system design, the baseline period is referred to as the assessment phase and is labeled as phase A. The treatment phase is labeled as phase B.

Question 2

When multiple treatments are used in the single-subject design, the first type of treatment is labeled A and the second treatment would be labeled as C and the third treatment would be labeled D and so forth.

Accepted Answer

The second treatment in a multiple treatment design is actually labeled B, not C.

Question 3

It is necessary for the number of measurements for the baseline and treatment periods to be equal.

Accepted Answer

While having an equal number of measurements for baseline and treatment periods can help in comparing changes and effects more directly, it is not strictly necessary. Research designs can be flexible, and the key is to have sufficient data to detect a meaningful difference or effect.

Question 4

It is not possible to engage in any form of statistical analysis of data, by measuring a single client one time before treatment and one time at the end of treatment.

Accepted Answer

Statistical analysis requires a comparison of data before and after treatment from multiple clients to draw meaningful conclusions. Measuring only one client before and after treatment does not provide a basis for statistical analysis.

Question 5

The standard deviation approach, in the case of the AB single-subject design, analyzes whether the treatment scores are enough standard deviations better than the baseline scores to be significantly different.

Accepted Answer

This is a true statement about the standard deviation approach in the AB single-subject design.

Question 6

When you use the upper two standard deviation method, you are answering the question whether the treatment mean is at least two standard deviations different than the baseline mean.

Accepted Answer

The upper two standard deviation method involves comparing the treatment mean to the baseline mean and determining if it is at least two standard deviations away from the baseline mean. This is a way to assess whether the treatment had a significant effect compared to the baseline.

Question 7

The standard deviation is a statistic that assumes independent data rather than paired data.

Accepted Answer

The standard deviation is a measure of variability that can be used with both independent and paired data. It measures how much the data is spread out from the mean.

Question 8

Not all evaluative researchers have the luxury of measuring the client on the target behavior or problem before treatment begins. This weakness can be dealt with by measuring the client several times during the first treatment period, followed by a change in the treatment while continuing to measure the client's target behavior or problem repeatedly during the second treatment period.

Accepted Answer

This approach is known as a multiple baseline design and is commonly used when pre-treatment measurements are not possible or feasible. By measuring the client's target behavior or problem repeatedly during both treatment periods, evaluative researchers can determine whether the change in treatment resulted in any significant improvements.

Question 9

When you use binomial test for the AB Design and when the data are measured as a dichotomy the statistical question to be answered is whether the pattern of positive baseline recording is significantly different from the treatment pattern of positive recordings.

Accepted Answer

This is a correct explanation of the question that can be answered using the binomial test for an AB design with dichotomous data. The test is used to compare the proportion of positive recordings in the baseline phase to the proportion of positive recordings in the treatment phase and determine if the difference is statistically significant.
