SPCE 630 FINAL EXAM
QUESTIONS AND ANSWERS 100%
CORRECT
Question 1: Threats to internal validity include: Testing, maturation, procedural infidelity
CORRECT ANSWER: History - 2A. Events that occur
during the experiment but that are not related to planned procedural changes that may influence the outcome Maturation - 2B. Changes in behavior due to the passage of time Testing - 2C. Occurs when participants need to respond to the same test repeatedly during a baseline or probe condition, which influences responding
Question 2: Threats related to the measurement system,
and are of concern because of repeated measurement by human observers who may make errors
CORRECT ANSWER: Data instability

Question 3: Inconsistent implementation of the
experimental condition
CORRECT ANSWER: Procedural infidelity
Question 4: The loss of participants during a study, which
limits the generality of findings
CORRECT ANSWER: Attrition
Question 5: Occurs when a participant's behavior is
influenced by more than one planned intervention during the course of a study
CORRECT ANSWER: Multiple treatment interference
Question 6: A type of data instability that refers to a
repeated and predictable pattern in the data series over time
CORRECT ANSWER: Cyclical variability
Question 7: 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
CORRECT ANSWER: Carryover Effects
Question 8: The hypothesis that states that there is no
significant difference between samples is:
CORRECT ANSWER: The Null Hypothesis
Question 9: 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
CORRECT ANSWER: Mean= 12, Median=11,
Mode=7,22

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:
CORRECT ANSWER: A Type 2 Error
Question 11: The primary purpose of the method section
is to:
CORRECT ANSWER: Detail the plan of study being
proposed. allows the readers to evaluate and judge the study's validity and reliability
Question 12: Which of the following is true about single
case research design?
CORRECT ANSWER: Most studies include one
participant
