SPCE 630 FINAL EXAM QUESTIONS & ANSWERS
Threats to internal validity - Answer -Testing, History, Maturation, Instrumentation,
Selection, Mortality
History - Answer -Events that occur during the experiment but are not related to
planned procedural changes that may influence the income
Maturation - Answer -Changes in behavior due to the passage of time
Testing - Answer -Occurs when participants need to respond to the same test
repeatedly during a a baseline or probe condition, which influences responding.
Data instability - Answer -Threats related to the measurement system, and are of
concern because of repeated measurement by human observers who may make errors
Procedural infidelity - Answer -Inconsistent implementation of the experimental
condition
Attrition - Answer -the loss of participants during a study
Multiple treatment interference - Answer -Occurs when a participants behavior is
influenced by more than one planned intervention during the course of a study
Cyclical variability - Answer -A type of data instability that refers to a repeated and
predictable pattern in the data series over time.
Carry over effects - Answer -occur when the effects of one treatment persist when
another treatment is introduced
The hypothesis that states that there is no significant difference between samples is -
Answer -null hypothesis
Amanda is an RBT at an ABA clinic. She is working with her client, Jerrell to decrease
aggressive behaviors (biting others). She has collected data for the frequency of jerrells
bites for 3 weeks. Calculate the mean, median, and mode of the following data set.
Week 1: 12,11,10,22,22
Week 2: 7,8,12,21,17
Week 3: 16,7,9,3,0 - Answer -Mean = 12
Median = 11
Mode = 7,12
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 ends. The school year, Dr. Jones concluded that the Good
Behavior Game has no impact on student on student disruptive behavior, when in fact it
had. This is an example of: - Answer -Type 2 error
The primary purpose of the method section is to - Answer -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.
Build a rationale for the study.
Both A and B are correct. (correct)
Which of the following is true about single case research design - Answer -Most studies
include more than one participant
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 btw
meaningful and trivial change - Answer -1. Group designs only have 1 or 2
measurement occasions
2. GD provide no info on which individuals subject changed
GD provide no info on how the individual subject changed
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 w 6 children
who have ASD. Jaclyn is using the tough kids social skills curriculum. The goal of the
social skills is to build basic social entry skills (make eye contact, greetings, etc). Prior
to the start of the group, kacyn collected data for each of the participants. She asked the
therapist to complete BASC -2 and also collected the frequency of spontaneous
greetings during a 30 min 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 -Frequency of spontaneous greetings
According to Carr and Briggs, practitioners of ABA should base their professional
activities on the research literature. One barrier is the cost of journal subscriptions. A
