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
, 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
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
