Watson-Glaser Critical Thinking Appraisal Interpretation 4 — Questions and Answers
Question 1: A financial analysis shows that companies in industries with strong union membership paid 12% higher average wages than those without. What is warranted by this data?
- Unions always increase wages by at least 12% in every industry.
- Higher union membership is associated with higher average wages in this analysis. (Correct answer)
- Workers should all join unions to guarantee a 12% pay increase.
- Companies without unions exploit their workers.
Correct answer: Higher union membership is associated with higher average wages in this analysis.
The data shows an association between union membership levels and wages but does not prescribe action or establish universal causation.
Question 2: A passage reports: 'Participants who meditated daily for 8 weeks reported a 40% reduction in perceived stress.' What does this finding most directly support?
- Meditation eliminates stress in most people within two months.
- Daily meditation for 8 weeks was associated with a 40% self-reported drop in perceived stress. (Correct answer)
- Stress reduction is impossible without meditation.
- The participants in this study no longer experience stress.
Correct answer: Daily meditation for 8 weeks was associated with a 40% self-reported drop in perceived stress.
The finding is about self-reported perceived stress in this participant group, not an objective or universal stress elimination.
Question 3: Traffic accident records show that most accidents in a city occur between 3 PM and 6 PM. Which is the most defensible interpretation?
- Drivers are more reckless during afternoon hours.
- The 3–6 PM window accounts for the highest number of recorded accidents in this city. (Correct answer)
- Driving should be restricted between 3 PM and 6 PM.
- Road conditions are worst during the late afternoon.
Correct answer: The 3–6 PM window accounts for the highest number of recorded accidents in this city.
The data records frequency of accidents by time and does not speak to driver behavior, road conditions, or policy solutions.
Question 4: A passage states that a new fertilizer increased crop yields by 25% in field trials. Which interpretation is most appropriate?
- All farms should immediately switch to the new fertilizer.
- The fertilizer produced 25% higher yields in the field trials conducted. (Correct answer)
- The new fertilizer is superior to all other fertilizers available.
- Crop yields will universally increase by 25% with this fertilizer.
Correct answer: The fertilizer produced 25% higher yields in the field trials conducted.
Field trial results support conclusions only about those trials, not universal or comparative claims.
Question 5: Data indicates that students in smaller class sizes (under 20) outperformed those in larger classes (over 30) on standardized tests by an average of 12 points. What is an over-interpretation of this data?
- Students in smaller classes scored higher on average in this dataset.
- There is a difference in test performance linked to class size in the data.
- Reducing class sizes guarantees every student's test scores will improve. (Correct answer)
- Class size appears related to student performance in standardized testing.
Correct answer: Reducing class sizes guarantees every student's test scores will improve.
Guaranteeing individual improvement for every student goes well beyond what group average data can support.
Question 6: A passage notes that a community garden project in a low-income neighborhood led to a 30% increase in residents reporting they 'feel connected to neighbors.' Which conclusion is best supported?
- Community gardens are the best way to improve social bonds in urban areas.
- Residents in this neighborhood reported feeling more connected after the garden project. (Correct answer)
- Low-income residents are always lonely without community initiatives.
- The garden project solved the neighborhood's social isolation problems permanently.
Correct answer: Residents in this neighborhood reported feeling more connected after the garden project.
The data reflects self-reported feelings in one neighborhood after one project and does not generalize or speak to permanence.
Question 7: A health report states: 'People who drink at least 8 glasses of water per day are 20% less likely to report headaches than those who drink fewer than 4 glasses.' What is the most justified interpretation?
- Dehydration is the primary cause of all headaches.
- Drinking 8 glasses of water daily will prevent headaches in everyone.
- Higher water intake was associated with lower self-reported headache rates in this group. (Correct answer)
- People who report headaches simply do not drink enough water.
Correct answer: Higher water intake was associated with lower self-reported headache rates in this group.
The data shows an association between water intake and headache reporting in this group, not a universal prevention claim.
