#1
Which of the following is NOT a type of research design in psychology?
Narrative research
ExplanationNarrative research focuses on storytelling rather than structured experimental designs.
#2
Which statistical measure describes the extent to which two variables are related to each other?
Correlation coefficient
ExplanationThe correlation coefficient quantifies the strength and direction of the relationship between two variables.
#3
Which of the following is a measure of central tendency?
Median
ExplanationThe median represents the central value of a dataset, dividing it into two equal halves.
#4
What is the purpose of a hypothesis in psychological research?
To predict the outcome of the study
ExplanationHypotheses are testable predictions about the relationship between variables in a study.
#5
Which of the following is a measure of dispersion?
Range
ExplanationThe range indicates the extent of variability or spread within a dataset, calculated by subtracting the smallest value from the largest.
#6
What is the primary purpose of random assignment in an experiment?
To minimize the influence of confounding variables
ExplanationRandom assignment helps distribute confounding variables equally among groups, reducing their impact on results.
#7
What is the purpose of a control group in an experiment?
To provide a baseline for comparison
ExplanationThe control group serves as a standard against which the effects of the experimental manipulation are compared.
#8
What is the purpose of informed consent in psychological research?
To ensure that participants are fully aware of the risks and benefits of participating
ExplanationInformed consent is essential for ensuring participants understand the nature of the study and give voluntary consent to participate.
#9

#12
Which of the following is an example of an independent variable?
Study duration
ExplanationAn independent variable is manipulated by the researcher and presumed to cause changes in the dependent variable.
#13
What is the purpose of a double-blind procedure in an experiment?
To eliminate experimenter bias
ExplanationDouble-blind procedures prevent bias by keeping both participants and experimenters unaware of group assignments.
