#1
What is the purpose of a control group in experimental research?
To provide a comparison for the experimental group
ExplanationOffers a standard for comparison against the experimental group.
#2
What is a single-subject design in applied behavior analysis?
A design that involves only one independent variable
ExplanationFocuses on one independent variable.
#3
What is the purpose of a baseline in single-subject research?
To establish a stable level of the dependent variable before introducing a treatment
ExplanationEstablishes a stable dependent variable level prior to treatment introduction.
#4
What is the purpose of a manipulation check in experimental research?
To assess the effectiveness of the independent variable manipulation
ExplanationEvaluates the effectiveness of independent variable manipulation.
#5
What is the purpose of a pilot study in experimental research?
To test the feasibility and refine the research procedures
ExplanationTests feasibility and refines research procedures.
#6
What is a within-subjects design in applied behavior analysis?
A design that involves comparing the same group of subjects under different conditions
ExplanationCompares the same subjects under various conditions.
#7
In a reversal design, what is the primary characteristic?
Systematic withdrawal and reintroduction of a treatment
ExplanationInvolves withdrawing and reintroducing treatment systematically.
#8
In a counterbalanced design, what is the main goal?
To balance the order of conditions across subjects
ExplanationAchieves balanced conditions order among subjects.
#9
What is a confounding variable in experimental research?
A variable that influences both the independent and dependent variables
ExplanationInfluences both independent and dependent variables.
#10
What is the purpose of a control variable in experimental research?
To eliminate confounding variables
ExplanationEliminates confounding variables' impact.
#11
In a multiple baseline design, what is unique about the timing of the introduction of the treatment across different baselines?
Treatment is introduced sequentially across different baselines
ExplanationSequential introduction of treatment across varied baselines.
#12
What is a factorial design in experimental research?
A design that involves manipulating two or more independent variables simultaneously
ExplanationSimultaneous manipulation of multiple independent variables.
#13
What is the difference between a parametric and nonparametric design in statistics?
Parametric designs assume normal distribution, while nonparametric designs do not make this assumption
ExplanationParametric assumes normal distribution; nonparametric does not.
#14
What is a Solomon four-group design?
A design that combines a pretest-posttest control group design with a posttest-only control group design
ExplanationCombines pretest-posttest and posttest-only control group designs.
#15
In a crossover design, what is a key characteristic?
Subjects are crossed over to different conditions in a random order
ExplanationSubjects cross over to conditions randomly.
