#1
What is the purpose of a control group in experimental design?
To compare the results of the experimental group with a baseline
ExplanationBaseline comparison in experimental groups.
#2
Which of the following is NOT a characteristic of a well-designed experiment?
Use of small sample size
ExplanationAvoidance of small sample sizes in well-designed experiments.
#3
What is the purpose of a reversal design in experimental psychology?
To observe the effects of an independent variable by removing it
ExplanationObserving effects by independent variable removal in reversal designs.
#4
In a multiple baseline design, what is the purpose of having multiple baselines?
To control for individual differences and demonstrate experimental control
ExplanationDemonstration of control and individual differences control with multiple baselines.
#5
What is the purpose of counterbalancing in experimental design?
To ensure that each participant experiences all experimental conditions in a different order
ExplanationEnsuring varied order of experimental conditions for participants.
#6
Which of the following is a disadvantage of using a within-subjects design?
Difficulty in controlling for order effects
ExplanationChallenges in controlling for order effects in within-subjects designs.
#7
What is the purpose of pilot testing in experimental design?
To obtain preliminary data and identify potential issues
ExplanationObtaining preliminary data and issue identification in pilot testing.
#8
Which of the following is NOT a potential threat to internal validity in experimental research?
Regression to the mean
ExplanationRegression to the mean as a non-threat to internal validity.
#9
What is a disadvantage of using a reversal design in experiments?
It may not be ethical to remove treatment from participants
ExplanationEthical concerns with treatment removal in reversal designs.
#10
What is a limitation of using a single-case experimental design?
Inability to generalize findings to larger populations
ExplanationGeneralization limitations in single-case experimental designs.
#11
In a crossover design, what is the primary advantage of using each participant as their own control?
Elimination of between-subject variability
ExplanationBetween-subject variability elimination by using participants as their own controls in crossover designs.
#12
What is a key consideration when using a factorial design in experiments?
Manipulation of more than one independent variable
ExplanationConsideration of multiple independent variable manipulation in factorial designs.
#13
What is the purpose of using a Latin square design in experimental research?
To control for order effects
ExplanationOrder effects control in Latin square designs.
#14
In a quasi-experimental design, what is a key difference from a true experimental design?
The absence of random assignment
ExplanationLack of random assignment as a key difference in quasi-experimental designs.
