Which research design allows researchers to determine cause and effect?
Ethnographic design
Experimental design
Correlational design
Case study design
In an experimental design, researchers manipulate an independent variable and control extraneous variables to observe a causal effect. Other designs do not allow definitive cause-effect conclusions.
Which sampling method gives each population member an equal chance of selection?
Purposive sampling
Convenience sampling
Stratified sampling
Simple random sampling
Simple random sampling ensures each member has an equal probability of selection, reducing sampling bias. Other methods involve deliberate selection or grouping.
Which data collection method is most suitable for gathering quantifiable data from a large sample?
Participant observation
In-depth interviews
Focus groups
Surveys with closed-ended questions
Surveys with closed-ended questions allow efficient collection of numeric data suitable for statistical analysis across large samples. Qualitative methods provide rich detail but limited generalizability.
Which measure describes the average value in a dataset?
Mean
Range
Variance
Median absolute deviation
The mean calculates the arithmetic average of observations, representing central tendency. Variance and range describe dispersion, not central value.
Which ethical principle requires researchers to obtain agreement from participants after informing them of the study?
Justice
Beneficence
Informed consent
Confidentiality
Informed consent ensures participants voluntarily agree after understanding study procedures. Beneficence and justice involve other ethical considerations, and confidentiality relates to data protection.
A study assessing dietary habits at a single point in time is best described as:
Cross-sectional study
Longitudinal study
Experimental study
Case-control study
Cross-sectional studies analyze data at one specific time, providing a snapshot of variables. Longitudinal studies follow subjects over time.
Stratified sampling primarily aims to reduce what?
Statistical significance threshold
Sample size
Sampling bias
Data collection time
Stratified sampling divides the population into homogeneous subgroups and samples from each, reducing sampling bias. It does not directly affect sample size or significance thresholds.
Recall bias is most likely in which study design?
Randomized controlled trial
Retrospective case-control study
Prospective cohort study
Cross-sectional survey
Retrospective case-control studies rely on participants' memories of past exposures, increasing recall bias risk. Prospective designs and RCTs collect data moving forward.
Which data collection method is ideal for exploring group dynamics and consensus?
Focus groups
Systematic observation
Structured interviews
Surveys with Likert scales
Focus groups facilitate discussion among participants to reveal group norms and consensus. Individual interviews and surveys lack this interactive feature.
A p-value indicates:
The probability of making a Type II error
The probability the null hypothesis is true
The effect size of the relationship
The probability of observing data given the null hypothesis is true
The p-value quantifies the probability of observing data given the null hypothesis, not the truth of the hypothesis itself. Effect size measures practical significance, and Type II error relates to beta errors.
A Type I error occurs when:
A true null hypothesis is rejected
A false alternative hypothesis is accepted
A true alternative hypothesis is rejected
A false null hypothesis is not rejected
A Type I error involves rejecting a true null hypothesis, representing a false positive. Type II errors involve failing to reject a false null.
Ensuring participant data cannot be traced back to individuals is known as:
Informed consent
Debriefing
Confidentiality
Anonymity
Anonymity means no identifying information is collected or linked to data. Confidentiality ensures data is protected but may still include identifiers.
Which qualitative approach focuses on understanding participants' lived experiences?
Phenomenology
Grounded theory
Experimental design
Content analysis
Phenomenology explores the essence of experiences from participants' perspectives. Grounded theory seeks theoretical models, and content analysis quantifies text data.
Mixed-methods research combines:
Qualitative and quantitative approaches
Meta-analysis and systematic review
Only quantitative techniques
Experimental and control groups
Mixed-methods research integrates qualitative and quantitative data for comprehensive understanding. Meta-analysis and systematic reviews are synthesis methods.
Convenience sampling is best described as:
Sampling based on predetermined quotas
Randomly selecting participants
Ensuring representation of subgroups
Selecting participants based on ease of access
Convenience sampling involves recruiting readily available participants, risking bias. Stratified or quota sampling aim for subgroup representation.
A quasi-experimental design differs from a true experiment mainly because:
It lacks manipulation of variables
It lacks random assignment of participants
It always uses qualitative methods
It cannot include control groups
Quasi-experiments manipulate variables but omit random assignment, risking selection biases. True experiments include both manipulation and randomization.
Multistage cluster sampling is most advantageous when:
Population elements are homogeneous
Geographic dispersion makes single-stage sampling difficult
A complete list of individuals is easily available
Stratification is not required
Multistage cluster sampling addresses dispersed populations by sampling clusters then individuals. It reduces logistical challenges when individual lists aren't accessible.
Factor analysis is primarily used to:
Test hypotheses about group differences
Reduce data dimensions by identifying underlying factors
Measure data reliability over time
Estimate sample size for studies
Factor analysis uncovers latent variables that explain correlations among observed measures, reducing dimensionality. Hypothesis testing and reliability involve other statistical methods.
Deception in research raises ethical concerns because:
It simplifies data collection procedures
It always causes physical harm
It may undermine participants' trust and autonomy
It has no effect on validity
Deception can harm trust and violate autonomy if participants are misled. Ethical oversight requires that it be justified and followed by debriefing.
In qualitative research, triangulation refers to:
Applying only one research technique consistently
Randomly assigning participants to groups
Using statistical tables to confirm results
Combining multiple data sources, methods, or theories for validation
Triangulation enhances credibility by cross-verifying findings through diverse sources or methods. It differs from random assignment or single-method approaches.
