C224 WGU MODULE 3 CHECKPOINT REVIEW MOST TESTED QUESTIONS AND
ANSWERS GRADED A+ WITH RATIONALES
1. Quantitative research is often noted for using a "narrow-angle" lens on study topics. Why
is this?
A) It focuses on a large number of causal factors
B) It focuses on one or two causal factors ⭐Correct Answer: B – It focuses on one or two causal
factors⭐
C) It focuses on subjective interpretations
D) It avoids using variables
Rationale: Quantitative research emphasizes control and precision, often isolating only one or
two causal factors to determine their specific effects.
2. For researchers looking to gather information regarding participant opinions, which tool is
recommended?
A) Observation
B) Rating scales ⭐Correct Answer: B – Rating scales⭐
C) Case studies
D) Archival data
Rationale: Rating scales quantify subjective opinions into measurable data, which is suitable for
statistical analysis.
3. Quantitative researchers focusing on individual phenomena make a concerted effort to
incorporate personal bias.
A) True
B) False ⭐Correct Answer: B – False⭐
C) Only in experimental research
D) Only in descriptive research
Rationale: Quantitative research seeks objectivity; personal bias is minimized to maintain
validity and reliability.
4. In studying specific phenomena, quantitative researchers attempt to include as much
personal bias as possible.
, ESTUDYR
A) True
B) False ⭐Correct Answer: B – False⭐
C) Only when necessary
D) Only in qualitative studies
Rationale: Objectivity is a hallmark of quantitative research; bias is avoided, not included.
5. Quantitative observation involves standardization of all procedures except which of the
following?
A) How observations are conducted
B) What to observe
C) When to observe
D) Why observations take place ⭐Correct Answer: D – Why observations take place⭐
Rationale: Quantitative research standardizes the procedure and variables, but the rationale
behind the observation is not standardized in data collection protocols.
6. If quantitative researchers utilize a nonrandom sample, it is also known as:
A) Randomized sample
B) Stratified sample
C) Biased sample ⭐Correct Answer: C – Biased sample⭐
D) Cluster sample
Rationale: Nonrandom sampling introduces potential bias, making the sample less
representative of the population.
7. Which of the following is NOT a function of variables in quantitative research?
A) Predict outcomes
B) Measure relationships
C) Discredit experiments ⭐Correct Answer: C – Discredit experiments⭐
D) Test hypotheses
Rationale: Variables are used to organize, test, and explain phenomena, not to discredit
research.
