NBT - National Benchmark Quantitative Literacy Data Interpretation Questions and Answers 2 — Questions and Answers
Question 1: A table shows the number of students achieving distinction (>75%) in Mathematics over 4 years: 2020=85, 2021=102, 2022=96, 2023=115. What is the range?
- 20
- 25
- 30 (Correct answer)
- 35
Correct answer: 30
Range = highest - lowest = 115 - 85 = 30.
Question 2: A graph shows that 360 out of 800 first-year students pass their first semester. What percentage failed?
- 44%
- 52%
- 55% (Correct answer)
- 60%
Correct answer: 55%
Passed: 360. Failed: 800 - 360 = 440. Percentage failed: (440 ÷ 800) × 100 = 55%.
Question 3: The following test scores are recorded: 45, 62, 78, 55, 62, 90, 62. What is the mode?
- 55
- 62 (Correct answer)
- 78
- 90
Correct answer: 62
The mode is the value that appears most frequently. 62 appears three times — more than any other value.
Question 4: A stacked bar chart shows a faculty of 500 students: 40% first-year, 35% second-year, 25% third-year. How many are third-year students?
- 100
- 115
- 125 (Correct answer)
- 150
Correct answer: 125
500 × 0.25 = 125 third-year students.
Question 5: A line graph shows rainfall increasing from 20 mm in January to 80 mm in March, then decreasing to 30 mm in May. By how many mm did rainfall increase from January to March?
- 40 mm
- 50 mm
- 60 mm (Correct answer)
- 70 mm
Correct answer: 60 mm
80 mm - 20 mm = 60 mm increase from January to March.
Question 6: A frequency table shows marks: 50–59 (8 students), 60–69 (12 students), 70–79 (15 students), 80–89 (5 students). How many students scored 70 or above?
- 15
- 18
- 20 (Correct answer)
- 22
Correct answer: 20
Students with 70–79: 15. Students with 80–89: 5. Total: 15 + 5 = 20 students.
