QUESTIONS AND ANSWERS 100%
CORRECT
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
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
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
