QUESTIONS WITH 100% VERIFIED
ANSWERS
Informed assent: - correct answers Includes obtaining consent from parents or legal guardians of minors
who are not yet old enough to enter into a contract
Threats to internal validity include - correct answers Testing, maturation, procedural infidelity
Applied research - correct answers involves systematic investigation related to the pursuit of knowledge
in practical realms or to solve real-world problems.
Events that occur during the experiment but that are not related to planned procedural changes that
may influence the outcomes. - correct answers History
Changes in behavior due to the passage of time - correct answers Maturation
Occurs when participants need to respond to the same test repeatedly during a baseline or probe
condition, whcih influences responding - correct answers Testing
Threats related to the measurement system, and are of concern because of repeated measurement by
human observers who may make errors - correct answers Instrumentation
Inconsistent implementation of the experimental condition - correct answers Procedural infidelity
The loss of participant's behavior is influenced by more than one planned intervention during the course
of a study - correct answers Multiple treatment interference
A type of data instability that refers to a repeated and predictable pattern in the data series over time -
correct answers cyclical variability
,Carryover effects: - correct answers A carryover effect is an effect of being tested in one condition on
participants' behavior in later/adjacent conditions and it is more difficult to address than sequence
effects.
The hypothesis that states that there is no significant difference between samples is: - correct answers
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 answers 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 answers A type I error
Dr. Jones wanted to know if the use of the Good Behavior Games 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 - correct answers Type 2 error
The primary purpose of the method section is to: - correct answers 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 answers The participant
serves as its own control
Or
Most studies include more than one participant
These graphs demonstrate which of the following - correct answers inter-subject replication with a
multiple baseline design across behaviors
These data show (q10) - correct answers A change in trend
Which of the following is a limitation of using statistical significance to differentiate between meaningful
and trivial change? - correct answers 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
All of the above (correct answer)
Which of the following is a limitation of group design? - correct answers Group designs only have one or
two measurement occasions.
Group designs provide no information on which individual subjects changed.
Group designs provide no information on how the individual subjects changed.
All of the above are potential limitations of group (correct answer)
