SPCE 630 FINAL EXAM QUESTIONS AND
ANSWERS 100% SOLVED 2026/2027 |
GRADED A+
Threats to internal validity include: - 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 - ANSWER -History
2B. Changes in behavior due to the passage of time -
ANSWER -Maturation
2C. Occurs when participants need to respond to the same
test repeatedly during a baseline or probe condition, which
influences responding - ANSWER -Testing
Threats related to the measurement system, and are of
concern because of repeated measurement by human
observers who may make errors -
ANSWER -Data instability
1 .
,Inconsistent implementation of the experimental condition -
ANSWER Procedural infidelity
The loss of participants during a study, which limits the
generality of findings - ANSWER -Attrition
Occurs when a participant's behavior is influenced by more
than one planned intervention during the course of a study -
ANSWER -Multiple treatment interference
A type of data instability that refers to a repeated and
predictable pattern in the data series over time - ANSWER -
Cyclical variability
Carryover Effects - 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
The hypothesis that states that there is no significant
difference between samples is: - ANSWER -The Null
Hypothesis
1 .
, 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 - 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: -
ANSWER -A Type 2 Error
The primary purpose of the method section is to: - ANSWER -
Detail the plan of study being proposed.
