1. Which of the following sampling methods ensures that every
member of the population has an equal chance of being selected?
A. Stratified sampling.
B. Systematic sampling.
C. Convenience sampling.
D. Simple random sampling.
Answer: d) Simple random sampling.
Rationale: Simple random sampling gives each member of the
population an equal chance of being selected, minimizing bias.
2. A hypothesis is typically tested through which process?
A. Data collection only.
B. Observation and analysis.
C. Statistical analysis and experimentation.
D. Reviewing literature.
Answer: c) Statistical analysis and experimentation.
Rationale: Hypotheses are tested through experimentation and
statistical analysis to determine if the data supports or refutes the
hypothesis.
,3. Which of the following data collection methods is best suited for
gathering in-depth insights into a person's thoughts or experiences?
A. Structured survey with closed-ended questions.
B. Observation of behavior in a natural setting.
C. In-depth interviews.
D. Secondary data analysis.
Answer: c) In-depth interviews.
Rationale: In-depth interviews allow researchers to explore a person's
thoughts, feelings, and experiences in a detailed and personal way.
4. Which statistical test is used to compare the means of two
independent groups?
A. Chi-square test.
B. T-test.
C. ANOVA.
D. Pearson’s correlation.
Answer: b) T-test.
Rationale: The T-test is used to determine if there is a significant
difference between the means of two independent groups.
5. A researcher wants to measure the effect of a new drug on blood
pressure. The control group in this experiment would likely receive:
A. A different drug.
, B. No treatment or a placebo.
C. Higher doses of the new drug.
D. The same dosage of the new drug.
Answer: b) No treatment or a placebo.
Rationale: A placebo or no treatment in the control group allows the
researcher to isolate the effect of the new drug by comparing it to a
group that did not receive the drug.
6. Which of the following is the most important factor in designing a
research experiment?
A. The size of the sample.
B. The complexity of the methodology.
C. The clarity and focus of the research question.
D. The time taken to complete the experiment.
Answer: c) The clarity and focus of the research question.
Rationale: A well-defined research question ensures that the
experiment is focused, making it easier to design a method that
addresses the problem effectively.
7. In an experiment, the variable that is measured as the outcome is
known as the:
A. Independent variable.
B. Dependent variable.
