#1

What is the independent variable in an experiment?

The variable that is measured
The variable that is manipulated
The variable that stays constant
The variable that is affected by other variables
#2

What is the purpose of a control group in an experiment?

To provide a comparison for the experimental group
To manipulate the independent variable
To ensure the participants are blind to the conditions
To prevent experimenter bias
#3

Which of the following is an example of a quasi-experimental design?

Randomized controlled trial
Cross-sectional study
Longitudinal study
None of the above
#4

What is the purpose of a placebo in experimental design?

To serve as a control group
To prevent researcher bias
To provide a baseline for comparison
To control for the placebo effect
#5

Which of the following is a potential disadvantage of a single-blind study?

Experimenter bias
Participant bias
Placebo effect
Demand characteristics
#6

What is a between-subjects design?

An experiment where participants are exposed to all conditions
An experiment where each participant is tested under multiple conditions
An experiment where different groups of participants are exposed to different conditions
An experiment where the researcher and participants are unaware of the conditions
#7

What is a factorial design in experimental psychology?

An experimental design that involves manipulating multiple independent variables
An experimental design that involves only one independent variable
An experimental design that involves manipulating multiple dependent variables
An experimental design that involves random assignment of participants
#8

What is the purpose of random assignment in experimental design?

To ensure that participants are representative of the population
To control for confounding variables
To minimize demand characteristics
To ensure that each participant has an equal chance of being in any condition
#9

What is a within-subjects design in experimental psychology?

An experimental design that involves manipulating multiple independent variables
An experimental design that involves only one independent variable
An experimental design that involves each participant being exposed to all conditions
An experimental design that involves random assignment of participants
#10

Which of the following is a disadvantage of a within-subjects design?

Requires fewer participants
Minimizes individual differences
Order effects may occur
Results are difficult to generalize
#11

What is a confounding variable in experimental design?

A variable that influences the dependent variable
A variable that is manipulated by the researcher
A variable that is controlled by randomization
A variable that is not accounted for and affects the results
#12

What is ecological validity in experimental design?

The extent to which findings can be generalized to real-world settings
The extent to which a study's results are consistent over time
The extent to which a study measures what it claims to measure
The extent to which a study's results can be replicated
#13

What is the purpose of counterbalancing in experimental design?

To ensure that each participant is tested under the same conditions
To control for order effects
To manipulate the independent variable
To minimize demand characteristics
#14

Which of the following is an example of a mixed design in psychology?

Repeated measures design
Between-subjects design
Quasi-experimental design
Factorial design
#15

What is the purpose of debriefing in experimental research?

To inform participants of the study's purpose after it is completed
To manipulate the independent variable
To ensure that participants are adequately compensated for their time
To prevent demand characteristics
#16

What is the difference between internal validity and external validity in experimental research?

Internal validity refers to the generalizability of results to other settings, while external validity refers to the accuracy of the measurements
Internal validity refers to the extent to which the study measures what it claims to measure, while external validity refers to the extent to which the results can be replicated
Internal validity refers to the extent to which the study's design allows causal inferences, while external validity refers to the generalizability of results to other populations
Internal validity refers to the control of confounding variables, while external validity refers to the control of demand characteristics
