Threats to internal validity include: - (answer)History, maturation, testing, procedural infidelity
Events that occur during the experiment but that are not related to planned procedural changes that
may influence the outcomes. - (answer)History
Changes in behavior due to the passage of time. - (answer)Maturation
Occurs when participants need to respond to the same test repeatedly during a baseline or probe
condition, which influences responding. - (answer)Testing
Threats related to the measurement system, and are of concern because of repeated measurement by
human observers who may make errors. - (answer)Instrumentation
Inconsistent implementation of the experimental condition. - (answer)Procedural Infidelity
The loss of participants during a study, which limits the generality of findings. - (answer)Attrition
Occurs when a participant's behavior is influenced by more than one planned intervention during the
course of a study. - (answer)Multiple Treatment Intreference
A type of data instability that refers to a repeated and predictable pattern in the data series over time. -
(answer)Cyclical Variability
Carryover effects: - (answer)NOT: Is best described as the effect of a procedure used in one condition on
responding in an adjacent condition.

The hypothesis that assumes that sample observations are influenced by some non-random cause is: -
(answer)The alternative hypothesis
Amanda is an RBT at an ABA clinic. She is working with her client, Jerrell, to decrease aggressive
behaviors (i.e., biting others). She has collected data for the frequency of Jerrell's bites for three weeks.
Calculate the mean, median, and mode of the following data set (round to the nearest whole number):
Week 1: 22, 31, 20, 32, 32
Week 2: 7, 8, 13, 31, 17
Week 3: 16, 5, 9, 12, 15 - (answer)Mean = 18, Median =16, Mode = 31, 32
Dr. Jones wanted to know if the use of the Good Behavior Game decreased rates of disruptive behaviors
in an elementary school. Dr. Jones collected data throughout the duration of the school year across two
elementary schools. In school A, all k-6 classrooms used the Good Behavior Game. In School B, no
classrooms used the Good Behavior Game. At the end of the school year, Dr. Jones shouted, "Eureka!
The Good Behavior Game works," when in fact it had no impact on student disruptive behavior. This is
an example of: - (answer)A Type I Error
The primary purpose of the literature review is to: - (answer)All of the above
Which of the following is true about single-case research design? - (answer)The participant serves as his
or her own control.
These graphs demonstrate which of the following: - (answer)Inter-subject replication with an A/B/A/B
design
These data show which of the following: - (answer)A change in variability

Which of the following is a limitation of using statistical significance to differentiate between meaningful
and trivial change? - (answer)NOT: Large enough sample sizes will always show a significant difference
between populations.
Which of the following is a limitation of group design? - (answer)All of the above are potential
limitations of group design.
Dr. Lestremau is employed in a large urban school district with 10 elementary schools. She wants to
evaluate the effects and feasibility of peer-mediated, school-based, discrete trial training for teaching
multiplication skills to six students with autism spectrum disorder. She will collect on-going and frequent
measurement of students' fluency with multiplication facts. Dr. Lestremau is using: - (answer)Single case
research design methodology
Kacyn is a BCBA at an ABA Center. She is running a small social skills group with 6 children who have
autism spectrum disorder. Kacyn is using the "Tough Kids Social Skills Curriculum." The goal of the social
skills sessions is to build basic social entry skills (e.g., making eye contact, greetings, responding to
name). Prior to the start of the group, Kacyn collected data for each of the participants. Specifically, she
asked the therapists to complete the BASC-2 (a rating scale that measures changes in behavior and
emotional status) and also collected the frequency of spontaneous greetings during a 30-minute
observation period. She continued to collect data for spontaneous greetings during and after
implementation of the social skills group. What is the dependent variable? - (answer)The frequency of
spontaneous greetings
According to Carr and Briggs (2010) practitioners of applied behavior analysis should base their
professional activities on the research literature. One barrier is the cost of journal subscriptions. A
solution suggested by Carr and Briggs (2010) includes: - (answer)Reading articles in journals, such as, the
Journal of Behavior Assessment and Intervention in Children, which provide articles for free.
Which of the following is the correct format for a parenthetical citation with 4 authors for the first
parenthetical citation in text (APA 7th edition) - (answer)(Dieringer et al., 2017)
