SPCE 630 FINAL EXAM – 63 QUESTIONS AND
ANSWERS
Threats to internal validity include: - -Testing, maturation, procedural
infidelity
-Match the definition. 2A. Events that occur during the experiment but that
are not related to planned procedural changes that may influence the
outcome - -History
-2B. Changes in behavior due to the passage of time - -Maturation
-2C. Occurs when participants need to respond to the same test repeatedly
during a baseline or probe condition, which influences responding - -Testing
-Threats related to the measurement system, and are of concern because of
repeated measurement by human observers who may make errors - -Data
instability
-Inconsistent implementation of the experimental condition - -Procedural
infidelity
-The loss of participants during a study, which limits the generality of
findings - -Attrition
-Occurs when a participant's behavior is influenced by more than one
planned intervention during the course of a study - -Multiple treatment
interference
-A type of data instability that refers to a repeated and predictable pattern
in the data series over time - -Cyclical variability
-Carryover Effects - --Refers for an effect of being tested in one state on
participants' behavior in later situations
- May occur in a within-subject trial when the effect of a particular level of
the self-independent variable persists even after the treatment finishes
-The hypothesis that states that there is no significant difference between
samples is: - -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: 12, 11, 10, 22, 22
, Week 2: 7, 8, 13, 21, 17
Week 3: 16, 7, 9, 3, 0 - -Mean= 12, Median=11, Mode=7,22
-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 concluded that the Good Behavior Game had no
impact on student disruptive behavior, when in fact it had. This is an
example of: - -A Type 2 Error
-The primary purpose of the method section is to: - -Detail the plan of study
being proposed.
allows the readers to evaluate and judge the study's validity and reliability
-Which fo the following is true about single case research design? - -Most
studies include one participant
-These data show which of the following: - -A change in variability
-Which of the following is a limitation of using statistical significance to
differentiate between meaningful and trivial change? - -All of the above
-Which of the following is a limitation of group design? - -All of the above
-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: - -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? - -The frequency of spontaneous greetings
