Threats to internal validity include
Testing, maturation, procedural infidelity
Events that occur during the experiment but that are not related to planned procedural changes that
may influence the outcomes.
History
Changes in behavior due to the passage of time.
Maturation
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.
Instrumentation
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 integrity
A type of data instability that refers to a repeated and predictable pattern in the data series over
time.
Cyclical Variability
Carryover effects:
????
NOT: Is best described as the effect of a procedure used in one condition on responding in an
adjacent condition.
Are more difficult to address than sequence effects.
May influence the participants' responding based on the order in which the experimental conditions
are introduced to participants.
Both A and B are correct.
, The hypothesis that assumes that sample observations are influenced by some non-random cause is:
The alternative 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 up 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
shouted, "Eureka! The Good Behavior Game works," when in fact it had no impact on student
disruptive behavior. This is an example of:
????
A Type I Error
NOT A Type 2 Error
A threat to internal validity
A threat to external validity
Cannot be determined based on the information provided.
The primary purpose of the method section is to:
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?
Most studies include more than one participant.
Which of the following is a limitation of using statistical significance to differentiate between
meaningful and trivial change?
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 are true.
Which of the following is a limitation of group design?
Group designs only have one or two measurement occasions.
