UMAT Data Interpretation 1 — Questions and Answers
Question 1: A bar chart shows hospital readmission rates of 15%, 22%, 18%, and 10% for four wards. What is the average readmission rate across all four wards?
- 16.25% (Correct answer)
- 65%
- 22%
- 15%
Correct answer: 16.25%
The average is calculated as (15 + 22 + 18 + 10) / 4 = 65 / 4 = 16.25%.
Question 2: A line graph shows patient recovery time decreasing from 10 days in 2018 to 6 days in 2023. What is the percentage decrease in recovery time?
- 40% (Correct answer)
- 60%
- 4%
- 34%
Correct answer: 40%
Percentage decrease = (10 - 6) / 10 × 100 = 4/10 × 100 = 40%.
Question 3: A pie chart shows 40% of clinic visits are for preventive care, 35% for acute illness, and 25% for chronic disease management. If the clinic sees 200 patients per week, how many visits are for chronic disease?
- 50 (Correct answer)
- 70
- 80
- 25
Correct answer: 50
25% of 200 = 0.25 × 200 = 50 patients per week for chronic disease management.
Question 4: A table shows Drug A has a success rate of 3/5 and Drug B has a success rate of 7/10. Which drug has the higher success rate?
- Drug A
- Drug B (Correct answer)
- They are equal
- Cannot be determined
Correct answer: Drug B
Drug A = 3/5 = 0.60 (60%), Drug B = 7/10 = 0.70 (70%) — Drug B has the higher success rate.
Question 5: A scatter plot shows a strong positive correlation between study hours and UMAT scores. What does this mean?
- Studying more causes a higher UMAT score
- Students who study more tend to score higher on the UMAT (Correct answer)
- All students who study score above average
- UMAT score is entirely determined by study hours
Correct answer: Students who study more tend to score higher on the UMAT
A positive correlation means that as one variable increases, the other tends to increase, but correlation does not imply causation.
Question 6: Data shows that a hospital reduced medication errors from 120 per month to 84 per month after implementing a new system. By what percentage did errors decrease?
- 30% (Correct answer)
- 36%
- 40%
- 70%
Correct answer: 30%
Percentage decrease = (120 - 84) / 120 × 100 = 36/120 × 100 = 30%.
