The hypothesis that assumes that sample observations are influenced by some non-
random cause is: - ANSWER-The alternative hypothesis
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)
A type of data instability that refers to a repeated and predictable pattern in the data
series over time. - ANSWER-Cyclical Variability
Which of the following is true about single-case research design? - ANSWER-The
participant serves as his or her own control.
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
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
Carryover effects: - ANSWER-NOT: Is best described as the effect of a procedure
used in one condition on responding in an adjacent condition.
The primary purpose of the literature review is to: - ANSWER-All of the above
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.
A BCBA calculated IOA for the above data set. IOA was reported as 16.6%. IOA
was calculated using which of the following: - ANSWER-Scored intervals
Which type of recording is a discontinuous measurement procedure? - ANSWER-
Partial interval recording
Two observers recorded whether hand-flapping occurred or did not occur during an
interval. Calculate IOA based on the Interval by Interval Method. - ANSWER-40%
What is a primary reason for replicating the findings of a study: - ANSWER-To
assess the generality of the study
