SPCE 630 EXAM
SPCE 630 EXAM QUESTIONS AND ANSWERS GRADED A+
Threats to internal validity include - correct answer Testing,
maturation, procedural infidelity
Events that occur during the experiment but that are not
related to planned procedural changes that may
influence the outcomes. - correct answer History
Changes in behavior due to the passage of time - correct answer
Maturation
Occurs when participants need to respond to the same
test repeatedly during a baseline or probe condition,
whcih influences responding - correct answer Testing
,SPCE 630 EXAM
Threats related to the measurement system, and are of
concern because of repeated measurement by human
observers who may make errors - correct answer
Instrumentation
Inconsistent implementation of the experimental
condition - correct answer Procedural infidelity
The loss of 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
,SPCE 630 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: 22, 31, 20, 32, 32
Week 2: 7, 8, 13, 31, 17
Week 3: 16, 5, 9, 12, 15 - correct answer Mean = 18, median
=16, Mode =31,32
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.
, SPCE 630 EXAM
Jones shouted, "Eureka! The Good Behavior Game
works," when in fact it had no impact on student
disruptive behavior. This is an example of: - correct answer A
type II error
The primary purpose of the method section is to: - correct
answer Both A and B
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.
Which of the following is true about single-case research
design? - correct answer Most studies include more than one
participant
These graphs demonstrate which of the following - correct
answer inter-subject replication with a multiple baseline
design across behaviors
These data show (q10) - correct answer A change in variability
