It involves studying one group or population.
It compares two or more groups or populations.
It focuses solely on qualitative analysis.
It relies on experimental designs exclusively.
#2
What is the primary aim of comparative research methods in psychology?
To generalize findings to a specific population.
To identify cause-and-effect relationships.
To compare psychological phenomena across different groups.
To conduct experiments in controlled environments.
#3
Which of the following is NOT a commonly used comparative research method in psychology?
Cross-sectional studies
Longitudinal studies
Case studies
Descriptive studies
#4
Which of the following is a potential limitation of comparative research methods in psychology?
Difficulty in establishing causality
High cost and resource-intensive nature
Limited generalizability to other populations
Subjectivity in data collection
#5
What is a key advantage of longitudinal studies in comparative research?
They provide insights into cause-and-effect relationships.
They allow for the examination of changes over time.
They are less time-consuming than other research methods.
They involve random assignment of participants to groups.
#6
What ethical considerations are important in comparative research involving human participants?
Informed consent and confidentiality
Random assignment and debriefing
Manipulation of variables and control groups
Data analysis and interpretation
#7
Which of the following is an example of a quasi-experimental design commonly used in comparative research?
Randomized controlled trial (RCT)
Pretest-posttest design
Factorial design
Single-case experimental design
#8
In comparative research, what does 'internal validity' refer to?
The extent to which findings can be generalized to other populations.
The degree to which a study accurately reflects the true relationship between variables.
The control over extraneous variables to isolate the effects of the independent variable.
The stability of results over time.
#9
Which of the following best describes the 'method of differences' in comparative research?
It involves observing and comparing similar groups over time.
It involves manipulating the independent variable to observe its effects on the dependent variable.
It entails examining how groups differ on a particular variable of interest.
It involves studying cases in depth to understand complex phenomena.
#10
Which statistical analysis technique is commonly used in comparative research to determine if there are significant differences between groups?
Factor analysis
Analysis of variance (ANOVA)
Chi-square test
Regression analysis
#11
What distinguishes cross-sectional studies from longitudinal studies in comparative research?
Cross-sectional studies examine different groups at a single point in time, while longitudinal studies follow the same group over time.
Longitudinal studies involve manipulating variables to observe their effects, while cross-sectional studies do not.
Cross-sectional studies control for extraneous variables more effectively than longitudinal studies.
Longitudinal studies are more cost-effective than cross-sectional studies.
#12
Which of the following best describes the 'method of agreement' in comparative research?
It involves observing and comparing similar groups over time.
It involves manipulating the independent variable to observe its effects on the dependent variable.
It entails examining how groups differ on a particular variable of interest.
It involves studying cases in depth to understand complex phenomena.
#13
In comparative research, what is the purpose of random sampling?
To ensure that all individuals have an equal chance of being selected for the study
To select participants based on specific criteria to represent different groups
To match participants in the experimental and control groups on key variables
To assign participants to different conditions of the experiment randomly
