Q.4 A study that collects data at a single point in time is called:
Longitudinal study
Cross-sectional study
Experimental study
Cohort study
Explanation - Cross-sectional studies examine a population at a single point in time to understand prevalence or relationships.
Correct answer is: Cross-sectional study
Q.5 Which research design is most appropriate to determine cause-and-effect relationships?
Descriptive
Experimental
Historical
Exploratory
Explanation - Experimental designs, especially randomized controlled trials, are ideal for establishing causality between variables.
Correct answer is: Experimental
Q.6 What is the main purpose of a descriptive research design?
To establish cause and effect
To describe characteristics of a population or phenomenon
To test hypotheses experimentally
To manipulate variables systematically
Explanation - Descriptive research aims to provide an accurate picture of characteristics, behaviors, or conditions of a population without manipulating variables.
Correct answer is: To describe characteristics of a population or phenomenon
Q.7 Which of the following is a non-experimental research design?
Randomized controlled trial
Pretest-posttest control group design
Cohort study
Factorial design
Explanation - Cohort studies observe participants over time without manipulation, making them non-experimental.
Correct answer is: Cohort study
Q.8 What is the primary focus of qualitative research in nursing?
Numerical measurement of variables
Statistical hypothesis testing
Understanding experiences, perceptions, and meanings
Manipulating variables to determine causality
Explanation - Qualitative research explores phenomena through the perspectives, experiences, and meanings of participants rather than numerical data.
Correct answer is: Understanding experiences, perceptions, and meanings
Q.9 Which of the following designs is most suitable for studying trends over time?
Cross-sectional design
Longitudinal design
Case study design
Exploratory design
Explanation - Longitudinal studies track changes in the same subjects over time to examine trends or development.
Correct answer is: Longitudinal design
Q.10 Which of these is a characteristic of a randomized controlled trial?
Non-random assignment
Random assignment to groups
No control group
Observational only
Explanation - RCTs involve random assignment of participants to experimental or control groups to minimize bias and establish causality.
Correct answer is: Random assignment to groups
Q.11 A research design that involves detailed examination of a single case or small number of cases is called:
Survey research
Case study design
Cohort study
Experimental research
Explanation - Case study research provides an in-depth exploration of a specific individual, group, or situation.
Correct answer is: Case study design
Q.12 Which type of research design is exploratory in nature?
Experimental
Qualitative
Descriptive
Randomized controlled trial
Explanation - Exploratory research often uses qualitative designs to investigate phenomena where little is known.
Correct answer is: Qualitative
Q.13 Which design is appropriate when studying rare diseases over time?
Case-control study
Cross-sectional study
Experimental study
Descriptive study
Explanation - Case-control studies are retrospective, comparing patients with a rare condition to those without to identify potential causes.
Correct answer is: Case-control study
Q.14 In which type of research design is the researcher primarily an observer?
Experimental
Quasi-experimental
Non-experimental
Factorial
Explanation - Non-experimental research, such as descriptive or correlational studies, involves observing without manipulating variables.
Correct answer is: Non-experimental
Q.15 Which of the following designs uses multiple groups and manipulates more than one variable?
Factorial design
Case study design
Cohort study
Descriptive design
Explanation - Factorial designs allow researchers to examine the effects of two or more independent variables simultaneously.
Correct answer is: Factorial design
Q.16 Which of the following is a limitation of cross-sectional studies?
Cannot determine cause-and-effect
Expensive and time-consuming
High dropout rate
Requires manipulation of variables
Explanation - Cross-sectional studies provide a snapshot at a single time point, so causal relationships cannot be inferred.
Correct answer is: Cannot determine cause-and-effect
Q.17 Quasi-experimental designs differ from true experimental designs because they:
Do not have a control group
Do not manipulate variables
Do not use random assignment
Do not collect data
Explanation - Quasi-experimental studies manipulate variables but lack random assignment, which may introduce some bias.
Correct answer is: Do not use random assignment
Q.18 Which design is best for generating new theories rather than testing existing ones?
Experimental
Descriptive
Grounded theory
Cohort study
Explanation - Grounded theory is a qualitative approach aimed at developing new theories based on data collected from participants.
Correct answer is: Grounded theory
Q.19 What is a major strength of longitudinal research?
Quick data collection
Cost-effectiveness
Ability to track changes over time
No risk of bias
Explanation - Longitudinal studies follow the same subjects over time, allowing researchers to observe changes and trends.
Correct answer is: Ability to track changes over time
Q.20 Which research design involves studying past records to answer research questions?
Experimental study
Historical research
Descriptive study
Correlational study
Explanation - Historical research examines past records, documents, and data to understand events or phenomena.
Correct answer is: Historical research
Q.21 Which design often uses interviews, focus groups, or observations to collect data?
Qualitative research
Experimental research
Descriptive survey
Randomized controlled trial
Explanation - Qualitative research relies on non-numerical data collection methods like interviews and observations to explore experiences and meanings.
