#5
What is a quasi-experimental design?

#6
What is the primary goal of descriptive research in psychology?
To describe and understand behavior
ExplanationAims to observe and comprehend behaviors.
#7
In an experiment, what is the purpose of random assignment?
To ensure that each participant has an equal chance of being assigned to any experimental group
ExplanationEliminates bias by randomly assigning participants.
#8
What is the term used to describe a measure that produces consistent results?
Reliability
ExplanationConsistency in measurement outcomes.
#9
Which of the following research methods is most appropriate for studying cause-and-effect relationships?
Experimental research
ExplanationAllows manipulation to determine causation.
#10
What is the placebo effect?
The phenomenon where participants in the control group experience changes due to their belief in receiving treatment
ExplanationChange in behavior due to belief in treatment.
#11
Which of the following best describes the concept of operationalization?
Defining abstract concepts in concrete terms
ExplanationTurning abstract concepts into measurable variables.
#12
What is a confounding variable in an experiment?
A variable that influences both the independent and dependent variables, leading to incorrect conclusions.
ExplanationExternal factor affecting study outcomes.
#13
In psychology, what does the term 'replication' refer to?
The process of repeating a study to see if the same results are obtained.
ExplanationEnsures reliability and validity of findings.
#14
What is the main advantage of longitudinal research design?
It allows for the study of developmental changes over time.
ExplanationObserving changes over extended periods.
#15
Which of the following is a limitation of correlational research?
It cannot establish cause-and-effect relationships.
ExplanationDoes not infer causation.
#16
What is the purpose of debriefing participants after a study?
To inform participants about the deception used in the study and address any potential negative consequences
ExplanationEnsures ethical treatment and understanding.
#17
Which of the following is an example of a quasi-experimental research design?

ExplanationLacks random assignment.
#18
What is the purpose of a literature review in scientific inquiry?
All of the above
ExplanationTo gather existing knowledge and guide research.
#19
Which of the following best describes the concept of construct validity?
The degree to which the operational definition of a variable accurately represents the underlying theoretical construct
ExplanationExtent to which measurements represent concepts.
#20
What is a confederate in psychology research?
An individual who pretends to be a participant but is actually working with the researcher
ExplanationAiding the researcher in experimental manipulation.
#21
Which statistical test is used to determine if there is a significant relationship between two variables?
Pearson correlation coefficient
ExplanationMeasures linear correlation between variables.
#22
What is the purpose of peer review in scientific research?
To provide feedback and improve the quality of research
ExplanationEnsures research meets standards and accuracy.
#23
Which ethical principle in research requires obtaining informed consent from participants?
Voluntary participation
ExplanationParticipants willingly agree to take part.
#24
What is the purpose of a null hypothesis in hypothesis testing?
To provide a basis for comparing the observed results with what would be expected by chance
ExplanationServes as a reference point for testing.
#25
What is the purpose of inferential statistics?
To determine the likelihood that the observed results are due to chance
ExplanationDrawing conclusions from sample data to population.
