1. In a single-case study evaluating a new intervention, how would you justify
the use of statistical analysis alongside visual analysis?
Using statistical analysis allows for the control of extraneous
variables, enhancing the reliability of the findings.
Statistical analysis is not needed if visual analysis shows clear trends.
Statistical analysis should only be used in group research designs.
Statistical analysis can confuse the results of single-case studies.
2. In the context of single-case research designs, explain the significance of the
term 'Verification' as it relates to A2 phases.
Verification refers to the process of confirming that the observed
effects of an intervention are consistent and replicable across
different phases of the study.
Verification indicates the end of the research process where results
are published.
Verification is the initial phase where predictions are made about the
intervention's effectiveness.
Verification is a method used to collect data during the intervention.
3. What is a common limitation of visual analysis studies as mentioned in the
text?
Data is collected from multiple sources
Data presented are generally decontextualized
Data is always presented in context
, Data is analyzed using qualitative methods
4. In a study comparing two interventions, if the results show significant
variability when both treatments are applied sequentially, what might this
indicate about the treatments?
It may indicate multiple treatment interference affecting the results.
It implies that the data representation was flawed.
It suggests that one treatment is superior to the other.
It confirms that both treatments are equally effective.
5. What is the definition of external validity in research?
Subjective feedback through opinion surveys, questionnaires, or
interviews
The extent to which the results from the study are applicable
outside the context of the study
The degree to which the research design controls for variables that
could support an alternative explanation for the findings
The degree to which two alternative assessments measure the same
behavior
6. Which best describes summative visual analysis?
Investigating the first phase change in a series of experimental
changes
Reviewing the effects after the completion of all phases to
determine overall effects
Examining how a change occurs during the length of a treatment
phase
,7. What is the definition of a type II error in the context of hypothesis testing?
Rejecting a true null hypothesis
Failing to accept a true null hypothesis
Accepting a true alternative hypothesis
Failing to reject a false null hypothesis
8. In a study evaluating the effectiveness of a new behavioral intervention,
researchers decide to implement a multiple baseline design across three
different classrooms. What is a potential benefit of this approach compared
to a traditional A/B design?
It allows for immediate implementation of the intervention without
baseline data.
It can demonstrate the intervention's effectiveness while controlling
for historical events that may affect the outcomes.
It requires fewer participants than the A/B design.
It is easier to analyze statistically than the A/B design.
9. Which of the following things can impact the external validity of a study?
the participants in the study
the measurements taken
all of the above can impact external validity
the location of the study
10. Dr. Watson was referred a 7-year-old African American female who suffered
a traumatic brain injury and engaged in public masturbation. Dr. Watson
evaluated the effects of response blocking with guided compliance and
, reinforcement for a habilitative replacement behavior to decrease public
masturbation and increase on-task behavior....
The concurrent multiple baseline design poses a problem for
researchers in applied settings because clients with similar target
behaviors may be referred at different points in time
The non-concurrent multiple baseline design allows the clinician to
better demonstrate experimental control compared to the
concurrent multiple baseline design
11. A 15-year-old teenager with autism struggles with social communication and
is having a hard time initiating and maintaining social interactions with peers.
Their father brought them into a clinic, and they wanted the BCBA to try to
increase their abilities to initiate and maintain social interactions. The BCBA
assesses their interactions and decides to use a combination of dyadic
instruction, modeling, and feedback to increase the skill set. The research
question that best fits the scenario is:
Does the combination of dyadic instruction, modeling, and feedback
aff
Does a combination of dyadic instruction, modeling, and feedback
increase initiations and maintenance of social interactions in a 15-
year-old boy?
Does an assessment of social skills increase initiating and maintaining
of social interactions?
Is there a correlation between social interactions and a combination
of dyadic instruction, modeling, and feedback?
12. Dr. Flores is conducting a meta-analysis of the available single-case research
design studies, which have evaluated procedures to train teachers to use
praise. Dr. Flores has coded each article and determined which to include.
The next step of the meta-analysis should be:
