Solutions Already Passed!!!
Threats to internal validity include - correct answer...✔✔Testing, maturation, procedural
infidelity
Events that occur during the experiment but that are not related to planned procedural
changes that may influence the outcomes. - correct answer...✔✔History
Changes in behavior due to the passage of time - correct answer...✔✔Maturation
Occurs when participants need to respond to the same test repeatedly during a baseline
or probe condition, whcih influences responding - correct answer...✔✔Testing
Threats related to the measurement system, and are of concern because of repeated
measurement by human observers who may make errors - correct answer...✔✔
Instrumentation
Inconsistent implementation of the experimental condition - correct answer...✔✔
Procedural infidelity
The loss of participant's behavior is influenced by more than one planned intervention
during the course of a study - correct answer...✔✔Multiple treatment interference
A type of data instability that refers to a repeated and predictable pattern in the data
series over time - correct answer...✔✔cyclical variability
Carryover effects: - correct answer...✔✔
The hypothesis that states that there is no significant difference between samples is: -
correct answer...✔✔The null 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 - correct 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: - correct answer...✔✔A type II error
The primary purpose of the method section is to: - correct answer...✔✔Both A and B
Detail the plan of study being proposed.
Provide a sufficiently detailed description of the study so a trained researcher can
implement the study as intended with no additional guidance.
Which of the following is true about single-case research design? - correct answer...✔
✔Most studies include more than one participant
These graphs demonstrate which of the following - correct answer...✔✔inter-subject
replication with a multiple baseline design across behaviors
These data show (q10) - correct answer...✔✔A change in variability
Which of the following is a limitation of using statistical significance to differentiate
between meaningful and trivial change? - correct answer...✔✔The rejection of the null
hypothesis is more decisive in larger sample sizes.
Large enough sample sizes will always show a significant difference between
populations
Statistical analysis may fail to reject the null hypothesis in small sample sizes
Which of the following is a limitation of group design? - correct answer...✔✔The
rejection of the null hypothesis is more decisive in larger samples
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: - correct 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? - correct answer...✔✔The frequency of spontaneous greetings
