SPCE 630 FINAL EXAM – QUESTIONS AND EXPERT
VERIFIED SOLUTIONS
Threats to internal validity include: Right Ans - 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 Right Ans - History
2B. Changes in behavior due to the passage of time Right Ans -
Maturation
2C. Occurs when participants need to respond to the same test repeatedly
during a baseline or probe condition, which influences responding Right
Ans - Testing
Threats related to the measurement system, and are of concern because of
repeated measurement by human observers who may make errors Right
Ans - Data instability
Inconsistent implementation of the experimental condition Right Ans -
Procedural infidelity
The loss of participants during a study, which limits the generality of
findings Right Ans - Attrition
Occurs when a participant's behavior is influenced by more than one
planned intervention during the course of a study Right Ans - Multiple
treatment interference
A type of data instability that refers to a repeated and predictable pattern
in the data series over time Right Ans - Cyclical variability
Carryover Effects Right Ans - -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: Right Ans - 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 Right Ans - 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: Right Ans - A Type 2 Error
The primary purpose of the method section is to: Right Ans - 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? Right
Ans - Most studies include one participant
These data show which of the following: Right Ans - A change in
variability
Which of the following is a limitation of using statistical significance to
differentiate between meaningful and trivial change? Right Ans - All of
the above
Which of the following is a limitation of group design? Right Ans - All of
the above
