FINAL EXAM / (NEW!)

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

pg. 2 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

pg. 3 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

pg. 4 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
