#1
Which of the following is NOT a type of psychological research method?
Logical reasoning
ExplanationLogical reasoning is not a formal psychological research method.
#2
What is the purpose of informed consent in psychological research?
To provide participants with information about the research study
ExplanationInformed consent ensures participants are aware of the study's purpose, procedures, and risks before participation.
#3
What is the purpose of debriefing participants in psychological research?
To inform participants about the true nature of the study after its completion
ExplanationDebriefing ensures participants understand the study's purpose, procedures, and any deception used.
#4
What is the purpose of descriptive statistics in psychological research?
To summarize and describe the characteristics of a data set
ExplanationDescriptive statistics provide an overview of data characteristics, such as central tendency and variability.
#5
What is the purpose of a frequency distribution in psychological research?
To summarize and describe the characteristics of a data set
ExplanationFrequency distributions display the frequency of different values in a dataset, aiding in data summary and analysis.
#6
What is the primary purpose of random assignment in experimental design?
To assign participants to different groups without bias
ExplanationRandom assignment helps prevent bias by evenly distributing participants into groups.
#7
What is a confounding variable in an experiment?
A variable that affects the dependent variable but is not controlled for
ExplanationConfounding variables are uncontrolled factors that influence the dependent variable.
#8
What is the difference between correlation and causation?
Correlation indicates a relationship between variables, while causation implies that one variable directly influences the other.
ExplanationCorrelation suggests a connection, while causation indicates a direct cause-and-effect relationship.
#9
Which of the following is an example of a quasi-experimental design?
A pretest-posttest design
ExplanationPretest-posttest designs lack random assignment, making them quasi-experimental.
#10
What is the purpose of a pilot study in psychological research?
To test the feasibility of the research design
ExplanationPilot studies help researchers refine their methods and assess the practicality of their study design.
#11
What is internal validity in experimental research?
The degree to which the experimental manipulation produces the intended effects
ExplanationInternal validity concerns the accuracy of conclusions drawn from experimental results.
#12
Which of the following is a disadvantage of experimental research?
It can be difficult to generalize findings to real-world settings
ExplanationExperimental findings may not always apply to real-world situations.
#13
What is the purpose of a control group in an experiment?
To serve as a baseline for comparison
ExplanationControl groups provide a reference point for evaluating the effects of the experimental manipulation.
#14
Which of the following is a potential ethical issue in psychological research?
Using deception without debriefing participants
ExplanationDeceptive practices should be followed by debriefing to inform participants of the true nature of the study.
#15
What is the difference between a correlation coefficient and a regression coefficient?
A correlation coefficient measures the strength and direction of a relationship, while a regression coefficient predicts the value of one variable based on another
ExplanationCorrelation coefficients quantify the relationship between variables, whereas regression coefficients predict values based on this relationship.
