Watson-Glaser Critical Thinking Appraisal Watson-Glaser Inference and Assumption Tests 2

Question 1

Statement: A tech company's internal audit found that teams using project management software completed tasks 18% faster on average than teams using email-only coordination. The audit covered 120 projects over two years and held team size constant. Based ONLY on the above, is this inference TRUE, PROBABLY TRUE, based on INSUFFICIENT DATA, or FALSE? Inference: Project management software improves team efficiency.

Accepted Answer

Probably True

Answer

The controlled audit strongly suggests this, but it is one company's data and may not universally apply.

Question 2

Statement: An assumption is something taken for granted, not proved. Statement: 'Teaching critical thinking in schools will produce better citizens.' Which of the following is an assumption made in this statement?

Accepted Answer

Critical thinking can be effectively taught in a school setting.

Answer

The recommendation assumes teaching critical thinking is feasible in schools — without this, the proposal collapses.

Question 3

Statement: Hospital data from the past decade shows that patients admitted on weekends had a 7% higher mortality rate than those admitted on weekdays. Staffing levels on weekends averaged 23% lower than on weekdays. Based ONLY on the above, is this inference TRUE, PROBABLY TRUE, based on INSUFFICIENT DATA, or FALSE? Inference: Lower weekend staffing levels are responsible for higher weekend mortality rates.

Accepted Answer

Probably True

Answer

The correlation between lower staffing and higher mortality is strong but does not prove causation alone.

Question 4

Statement: A study tracked 2,000 adults who began a daily 30-minute walking programme. After 12 months, 74% reported reduced stress levels. The study did not measure physical health outcomes. Based ONLY on the above, is this inference TRUE, PROBABLY TRUE, based on INSUFFICIENT DATA, or FALSE? Inference: Walking reduces blood pressure.

Accepted Answer

Insufficient Data

Answer

The passage only covers stress levels, not blood pressure. There is no data to judge this inference.

Question 5

Statement: An assumption is something taken for granted, not proved. Statement: 'If we lower the price of our product, we will increase total sales revenue.' Which of the following is an assumption made in this statement?

Accepted Answer

The increase in units sold will more than offset the lower price per unit.

Answer

Revenue = price × volume. The statement assumes volume gains will outweigh the price cut — this is the core unstated premise.
