VERIFIED ANSWERS
1. Threats to internal validity include:ANS: Testing, maturation, procedural
infidelity
2. Match the definition. 2A. Events that occur during the experiment but
thatare not related to planned procedural changes that may influence the
out- come:ANS: History
3. 2B. Changes in behavior due to the passage of time:ANS: Maturation
4. 2C. Occurs when participants need to respond to the same test repeatedly
during a baseline or probe condition, which influences responding:ANS:
Testing
5. Threats related to the measurement system, and are of concern because
of repeated measurement by human observers who may make errors:ANS:
Datainstability
6. Inconsistent implementation of the experimental condition:ANS:
Procedural infi-delity
7. The loss of participants during a study, which limits the generality of
find-ings:ANS: Attrition
8. Occurs when a participant's behavior is influenced by more than one
planned intervention during the course of a study:ANS: Multiple treatment
interfer-ence
1/7
, 9. A type of data instability that refers to a repeated and predictable pattern in
the data series over time:ANS: Cyclical variability
10. Carryover Effects:ANS: -Refers for an effect of being tested in one state
on partici-pants' behavior in later situations
- May occur in a within-subject trial when the effect of a particular
level of theself-independent variable persists even after the treatment
finishes
11. The hypothesis that states that there is no significant difference between
samples is:ANS: The Null Hypothesis
12. 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 datafor 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):ANS: Week 1:ANS: 12, 11, 10, 22, 22
Week 2:ANS: 7, 8, 13, 21, 17
Week 3:ANS: 16, 7, 9, 3, 0:ANS: Mean= 12, Median=11, Mode=7,22
13. 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:ANS: A Type
