UCAT Numerical Data Interpretation 1 — Questions and Answers
Question 1: A table shows that Hospital A had 2,400 admissions in Q1 and Hospital B had 1,800. What percentage more admissions did Hospital A have compared to Hospital B?
- 25%
- 30%
- 33% (Correct answer)
- 40%
Correct answer: 33%
(2400 − 1800) / 1800 × 100 = 600 / 1800 × 100 ≈ 33%.
Question 2: A graph shows surgery waiting times (weeks): Jan = 6, Feb = 8, Mar = 7, Apr = 5. What is the mean waiting time over the 4 months?
- 5.5 weeks
- 6.0 weeks
- 6.5 weeks (Correct answer)
- 7.0 weeks
Correct answer: 6.5 weeks
(6 + 8 + 7 + 5) / 4 = 26 / 4 = 6.5 weeks.
Question 3: A chart shows that 360 out of 1,200 outpatient appointments were missed. What is the did-not-attend (DNA) rate?
- 25%
- 30% (Correct answer)
- 33%
- 40%
Correct answer: 30%
360 / 1,200 × 100 = 30% DNA rate.
Question 4: Emergency admissions data: Monday 45, Tuesday 60, Wednesday 50, Thursday 55, Friday 70. What is the median number of admissions?
- 50
- 55 (Correct answer)
- 57
- 60
Correct answer: 55
Ordered: 45, 50, 55, 60, 70 — the middle value (median) is 55.
Question 5: A pie chart shows hospital budget allocation: salaries 55%, equipment 20%, maintenance 15%, other 10%. If the total budget is $2,000,000, how much is spent on maintenance?
- $250,000
- $300,000 (Correct answer)
- $350,000
- $400,000
Correct answer: $300,000
15% of $2,000,000 = 0.15 × 2,000,000 = $300,000 for maintenance.
Question 6: A bar chart shows infection rates per 1,000 bed days: Ward A = 2.5, Ward B = 3.0, Ward C = 1.5, Ward D = 4.0. Which ward has the rate closest to the overall average?
- Ward A
- Ward B (Correct answer)
- Ward C
- Ward D
Correct answer: Ward B
Average = (2.5 + 3.0 + 1.5 + 4.0) / 4 = 11 / 4 = 2.75; Ward B's rate of 3.0 is closest to 2.75.
