#1
Which of the following best defines experimental design?
The process of selecting participants for a study.
The plan for conducting an experiment to test a hypothesis.
The statistical analysis of experimental results.
The interpretation of data collected during an experiment.
#2
What is the main purpose of a control group in an experiment?
To provide a baseline for comparison.
To introduce bias into the experiment.
To ensure the experiment runs smoothly.
To manipulate the independent variable.
#3
Which of the following is a measure of variability in a dataset?
Standard deviation
Mean
Mode
Median
#4
What is the purpose of randomization in experimental design?
To ensure that each participant has an equal chance of being assigned to any experimental condition.
To guarantee that the experiment will produce significant results.
To control for extraneous variables.
To eliminate the need for a control group.
#5
What is the purpose of blinding in experimental design?
To hide the results of the experiment.
To ensure that participants are not harmed.
To prevent biases in the experimental procedure.
To increase the sample size.
#6
Which of the following is NOT a threat to internal validity in an experiment?
Selection bias
Regression to the mean
History effect
Maturation
#7
What is the purpose of conducting a pilot study in experimental research?
To test the reliability of the experimental procedure.
To recruit participants for the main study.
To analyze the data collected in the main study.
To publish preliminary findings.
#8
Which of the following is NOT a type of experimental design?
Within-subjects design
Quasi-experimental design
Cross-sectional design
Longitudinal design
#9
In a repeated measures design, what does each participant experience?
Multiple levels of the independent variable.
Different experimental conditions.
The same experimental condition multiple times.
A combination of independent variables.
#10
What is the difference between systematic and random variability?
Systematic variability is planned, while random variability is not.
Systematic variability can be controlled, while random variability cannot.
Systematic variability is always present, while random variability is rare.
Systematic variability is due to chance, while random variability is predictable.
#11
Which of the following is a potential drawback of using a between-subjects design?
Increased variability
Greater sensitivity to individual differences
Reduced statistical power
Difficulty in detecting treatment effects
#12
Which of the following best describes a factorial design?
A design that includes only two levels of the independent variable.
A design that manipulates multiple independent variables.
A design that uses a control group and an experimental group.
A design that involves random assignment of participants to conditions.
#13
What is the purpose of counterbalancing in experimental design?
To ensure that participants are not influenced by the experimenter's expectations.
To control for order effects in within-subjects designs.
To reduce variability in the dependent variable.
To prevent demand characteristics.
#14
Which of the following is a potential drawback of using a within-subjects design?
Increased variability
Greater sensitivity to individual differences
Reduced statistical power
Difficulty in detecting treatment effects
