SPCE 630 FINAL EXAM
SPCE 630 FINAL EXAM QUESTIONS AND ANSWERS GRADED A+
Threats to internal validity include: - correct answer 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 - correct answer History
2B. Changes in behavior due to the passage of time - correct answer
Maturation
2C. Occurs when participants need to respond to the same test
repeatedly during a baseline or probe condition, which
influences responding - correct answer Testing
,SPCE 630 FINAL EXAM
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
Inconsistent implementation of the experimental condition -
correct answer Procedural infidelity
The loss of participants during a study, which limits the
generality of findings - correct answer Attrition
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
A type of data instability that refers to a repeated and
predictable pattern in the data series over time - correct answer
Cyclical variability
Carryover Effects - correct answer -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
, SPCE 630 FINAL EXAM
The hypothesis that states that there is no significant difference
between samples is: - correct answer 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 - correct answer 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: - correct answer A Type 2 Error
