To assess the correlation between two variables
To compare means of three or more groups
To test the significance of a regression coefficient
#6
What is the purpose of a control group in an experiment?

#7
Which statistical measure is used to measure the central tendency of a set of scores?
Standard deviation
Mean

T-test
#8
What is a confounding variable in experimental research?
The variable that is manipulated by the researcher
An extraneous variable that is not controlled for and may affect the dependent variable
The variable that is measured in the study
A variable that only affects the independent variable
#9
Which research design is characterized by the manipulation of an independent variable and random assignment of participants to conditions?
Correlational design
Longitudinal design
Experimental design
Cross-sectional design
#10
In survey research, what is a Likert scale?
A type of experimental manipulation
A statistical measure of correlation
A method of random sampling
A scale for measuring attitudes using a range of responses
#11
What is a quasi-experimental design in research?
A design with no control group
A design that lacks random assignment
A design with only one dependent variable
A design with no independent variable
#12
What is a double-blind procedure in experimental research?
When both the experimenter and participants are unaware of the experimental conditions
When only the experimenter is unaware of the experimental conditions
When only the participants are unaware of the experimental conditions
When the experiment is conducted twice with different conditions
#13
In survey research, what is a response bias?
A type of statistical error
A systematic pattern of inaccurate responses
The range of responses in a survey
The average response rate in a survey
#14
What is the primary purpose of an Institutional Review Board (IRB) in psychological research?
To analyze and interpret research findings
To ensure the ethical treatment of research participants
To determine the statistical significance of results
To design research studies
#15
What does it mean if research findings are statistically significant?
The findings have practical significance
The results occurred by chance
The results are unlikely to have occurred by random variation alone
The study has a large sample size
#16
What is the purpose of random assignment in experimental research?
To ensure that participants are similar at the beginning of the study
To manipulate the independent variable
To increase the external validity of the study
To control for confounding variables
#17
What is the difference between reliability and validity in research measurement?
Reliability refers to consistency, while validity refers to accuracy
Reliability refers to accuracy, while validity refers to consistency
They are synonymous and can be used interchangeably
Reliability and validity both refer to the precision of measurement
