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.

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.

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
