Which characteristic is essential for a well-formulated research question?
Clarity and focus
Broad and vague scope
Irrelevance to study objectives
Based on assumptions rather than evidence
A well-formulated research question must be clear and focused to guide study design and ensure research objectives are met. Vague or overly broad questions lead to confusion and poor methodology. According to Scribbr, clarity ensures the researcher and readers understand the study’s scope. Scribbr.
What does it mean for a research question to be testable?
It can be empirically investigated through data
It is based solely on opinions
It cannot be measured or observed
It remains entirely theoretical
A testable research question is one that can be operationalized and examined using empirical methods. Without testability, the question cannot yield measurable data or valid conclusions. Testability distinguishes scientific inquiry from speculation. ScienceDirect.
Which of the following is an example of an explanatory research question?
How does social media use influence academic performance among college students?
What are students’ opinions about social media?
How many hours do students spend on social media?
Is there any use of social media?
Explanatory research questions seek to understand causal relationships between variables. This example asks how one variable (social media use) affects another (academic performance). By focusing on influence, it goes beyond description and seeks explanation. Scribbr.
In hypothesis testing, the null hypothesis (H0) typically states _____?
No effect or no difference
A specific effect exists
The theory is proven correct
The researcher's personal prediction
The null hypothesis posits that there is no relationship or effect between the variables under study. It serves as the default assumption to be tested against the alternative hypothesis. Rejection of H0 suggests evidence for an effect. Statistics by Jim.
Which of the following is a directional hypothesis?
Students who study with music will score higher on tests than those who study in silence.
Music affects test scores.
Study environment influences performance.
There is a relationship between music and study habits.
A directional hypothesis specifies not only that a relationship exists but also its expected direction. This example predicts that one group will perform better than another. Directional hypotheses are more specific and allow for one-tailed tests. SAGE Research Methods.
What term describes the variable that is manipulated or changed by the researcher?
Independent variable
Dependent variable
Extraneous variable
Confounding variable
The independent variable is the factor that the researcher actively manipulates to observe its effect on another variable. It is the presumed cause in an experimental design. Proper identification ensures accurate testing of hypotheses. Britannica.
What term describes the variable that is measured and expected to change in response to the independent variable?
Dependent variable
Independent variable
Control variable
Moderator variable
The dependent variable is the outcome measure that is hypothesized to change when the independent variable is manipulated. It represents the effect in an experimental study. Accurately defining it is crucial for valid results. Explorable.
Which of these is NOT an appropriate research question for a quantitative study?
How do patients describe their experiences with telehealth services?
What is the average wait time for telehealth appointments?
Does telehealth reduce healthcare costs?
Is there a correlation between telehealth use and patient satisfaction scores?
Quantitative studies focus on numerical data and statistical relationships. Asking how patients describe experiences is qualitative in nature. The other options can be answered with measurable data. SAGE Research Methods.
Which element is NOT part of the SMART criteria for research questions?
Theoretical
Time-bound
Measurable
Achievable
SMART stands for Specific, Measurable, Achievable, Relevant, and Time-bound. Theoretical is not one of the SMART elements. Using SMART ensures clear and realistic research goals. Project Smart.
In the PICO framework for formulating research questions, what does 'C' represent?
Comparison
Context
Conclusion
Criteria
PICO stands for Population, Intervention, Comparison, and Outcome. The 'C' helps define what the intervention will be compared against. This framework is widely used in clinical and evidence-based research. USC Libraries.
What does operationalization of a variable involve?
Defining it in measurable terms
Assigning random values
Ignoring its effect
Theorizing without measurement
Operationalization is the process of defining how a concept will be measured in practical terms. It bridges abstract variables and concrete data collection. Clear operational definitions improve reliability and validity. Simply Psychology.
Which statement best defines an alternative hypothesis?
It predicts a specific relationship or effect
It assumes no relationship exists
It is the same as the null hypothesis
It cannot be tested
The alternative hypothesis (H1) asserts that there is a relationship or effect between variables. It is what the researcher aims to support through statistical testing. H1 complements the null hypothesis and guides the direction of research. Statistics by Jim.
How does a research hypothesis differ from a research question?
A hypothesis makes a declarative prediction; a question asks for information
A hypothesis asks for information; a question predicts outcomes
They are synonyms
A hypothesis is always qualitative; a question is quantitative
A research question asks what the study aims to find out, while a hypothesis predicts the relationship between variables. Questions are open-ended, and hypotheses are testable statements. Distinguishing them clarifies study design. NCBI.
Which type of research question is most appropriate for a qualitative study?
What are the lived experiences of refugees adapting to a new country?
How many refugees resettle in an urban area annually?
Does counseling improve refugee integration rates?
What is the statistical relationship between length of residency and employment?
Qualitative research questions explore perceptions, experiences, and meanings. This question seeks descriptive, contextual insights. Quantitative questions would focus on counts or relationships. SAGE Research Methods.
In quantitative research, a hypothesis that specifies no relationship between variables is called the ____?
Null hypothesis
Alternative hypothesis
Directional hypothesis
Associative hypothesis
The null hypothesis (H0) posits that there is no statistical relationship or effect between the variables. It serves as a baseline that the alternative hypothesis challenges. Most statistical tests assess whether data allow rejection of H0. Investopedia.
To narrow the scope of a broad research question, a researcher should:
Identify specific variables and contexts
Include multiple populations and outcomes
Keep the question open-ended
Avoid defining key terms
Narrowing scope involves focusing on particular variables and situational boundaries. This enhances feasibility and clarity in data collection. Broad questions can dilute study impact and lead to ambiguous results. Scribbr.
Which example represents a non-directional hypothesis?
There is a relationship between sleep duration and cognitive performance.
Non-directional hypotheses state that a relationship exists without specifying its direction. This allows for two-tailed tests in statistical analysis. It is useful when theoretical grounds for directionality are weak. Britannica.
Which variable type is exemplified by 'blood type'?
Categorical nominal
Continuous interval
Ordinal scale
Ratio scale
Blood type categories (A, B, AB, O) are nominal because they represent distinct groups without intrinsic order. Nominal variables label categories qualitatively. Proper classification guides appropriate statistical tests. Laerd Statistics.
Which research question is suitable for a correlational study?
Is there an association between stress levels and blood pressure?
What interventions reduce stress?
How do students describe stress at exams?
Does stress cause hypertension?
Correlational studies assess the strength and direction of relationships between variables without inferring causality. Asking about association fits this design. Intervention or causal questions require experimental methods. Scribbr.
Falsifiability in hypothesis formulation means:
The hypothesis can be tested and potentially disproven
It is always proven true
It cannot be measured
It requires subjective interpretation
A falsifiable hypothesis makes clear predictions that can be empirically refuted if false. This principle is central to the scientific method. Hypotheses that cannot be tested or disproven are not scientifically useful. Stanford Encyclopedia of Philosophy.
A pilot study primarily aims to:
Test the feasibility of research design
Present final conclusions
Recruit participants for the main study
Publish preliminary results
Pilot studies are small-scale trials used to refine methodology and identify potential issues before the main study. They help assess feasibility, reliability, and validity of procedures. Findings guide adjustments to the full research protocol. NCBI.
Type I error occurs when:
Rejecting a true null hypothesis
Failing to reject a false null hypothesis
Accepting a true alternative hypothesis
Both hypotheses are correct
A Type I error happens when the researcher incorrectly rejects the null hypothesis even though it's actually true. This is also known as a false positive. Controlling the significance level (alpha) helps limit this error risk. Statistics How To.
When formulating hypotheses for a factorial design with two independent variables, one should consider:
Main effects and interaction effects between variables
Only main effects of each variable
Only interaction effects
Confounding of all variables
Factorial designs allow analysis of each variable’s main effect as well as any interaction between them. Considering both ensures comprehensive understanding of combined influences. Ignoring interactions can miss critical insights. Britannica.
A compound research question is characterized by:
Addressing more than one aspect or variable within one question
Focusing on a single variable only
Comparing hypotheses explicitly
Being non-testable
Compound questions combine multiple elements or variables, which can complicate study design and analysis. They often require breaking down into separate, clear questions. Well-structured research questions should focus on a single relation for clarity. Scribbr.
In hypothesis testing, a moderator variable is one that:
Alters the strength or direction of the relationship between independent and dependent variables
Is the same as a mediator
Is always extraneous
Remains unmeasured
A moderator variable affects the magnitude or direction of the effect between an independent and dependent variable. Identifying moderators helps explain under what conditions relationships hold. This is key for nuanced theory development. SAGE Research Methods.

Cheat Sheet
Differentiating Purpose, Questions, and Hypotheses -
A clear purpose statement outlines the "why" of a study (e.g., "to examine the impact of study apps on exam performance"). Research questions narrow focus into specific inquiries, such as "How does app usage relate to test scores?" Hypotheses predict relationships (e.g., "Students who use study apps score 10% higher than those who don't").
Formulating Testable Hypotheses -
Distinguish between null (Hâ‚€) and alternative (Hâ‚) hypotheses; the null always states "no effect" while the alternative predicts a directional or non-directional change. For example, Hâ‚€: "There is no difference in retention between flashcard and lecture methods," versus Hâ‚: "Flashcards improve retention more than lectures." This clarity is critical for statistical testing.
Using the FINER Criteria -
Ensure each question is Feasible, Interesting, Novel, Ethical, and Relevant (FINER), a mnemonic from clinical research design (Hulley et al., 2013). For instance, ask "Does a 4-week mindfulness app reduce stress among college students?" to verify feasibility and relevance before diving into data collection.
PICO Framework for Structured Questions -
In health and social research, use PICO (Population, Intervention, Comparison, Outcome) to craft precise questions: "In freshman students (P), does daily journaling (I) versus no journaling (C) improve GPA (O) after one semester?" This template boosts clarity and guides literature searches.
Identifying Variables Correctly -
Label your independent variable (cause) and dependent variable (effect) to avoid confusion - e.g., "study duration" (IV) and "quiz score" (DV). Remember: IV comes first alphabetically ("I" before "D"), helping you build accurate hypotheses and data tables.
