EDPT Data Interpretation and Table Reading 5 — Questions and Answers
Question 1: A table shows response times (seconds) for five database queries: Q1=0.8, Q2=2.3, Q3=1.1, Q4=0.5, Q5=1.9. What is the range of response times?
- 1.8 (Correct answer)
- 1.3
- 2.3
- 0.9
Correct answer: 1.8
Range = maximum minus minimum = 2.3 − 0.5 = 1.8 seconds.
Question 2: A two-column table lists employees and their monthly keystrokes (thousands): Alice=420, Bob=385, Carol=510, Dave=395. Carol's keystrokes are approximately what percent more than Bob's?
- 32% (Correct answer)
- 24%
- 19%
- 28%
Correct answer: 32%
(510−385)/385 × 100 ≈ 32.5%, so approximately 32% more than Bob.
Question 3: A table shows records processed per batch: Batch 1=1,200, Batch 2=950, Batch 3=1,450, Batch 4=800, Batch 5=1,100. Which two consecutive batches have the smallest combined total?
- Batch 4 and Batch 5 (Correct answer)
- Batch 1 and Batch 2
- Batch 2 and Batch 3
- Batch 3 and Batch 4
Correct answer: Batch 4 and Batch 5
Batch 4+5 = 800+1100 = 1900, which is less than any other consecutive pair sum.
Question 4: A table shows the number of software bugs by category: Logic=45, Syntax=30, Runtime=25, UI=20. What fraction of all bugs are Runtime or UI bugs?
- 3/8 (Correct answer)
- 1/4
- 9/20
- 2/5
Correct answer: 3/8
Runtime+UI = 45; Total = 120; 45/120 = 3/8.
Question 5: A table displays login attempts by user role over one week — Admin: Successful=48, Failed=2; User: Successful=312, Failed=18. Which role has a higher failure rate?
- User (Correct answer)
- Admin
- Both are equal
- Cannot be determined
Correct answer: User
Admin failure rate = 2/50 = 4%; User failure rate = 18/330 ≈ 5.5%; Users have the higher failure rate.
Question 6: A table shows disk read speeds (MB/s) under different loads: Idle=550, Low=480, Medium=390, High=210. What is the percentage decrease from Idle to High load?
- 61.8% (Correct answer)
- 58.2%
- 73.6%
- 47.4%
Correct answer: 61.8%
(550−210)/550 × 100 = 340/550 × 100 ≈ 61.8%.
Question 7: A table lists data center temperature readings (°F) at four times: 6AM=68, 12PM=74, 6PM=71, 12AM=66. At which reading time is the temperature exactly halfway between the day's minimum and maximum?
- 6PM (Correct answer)
- 12PM
- 6AM
- 12AM
Correct answer: 6PM
Min=66, Max=74; midpoint = (66+74)/2 = 70; 6PM reading of 71 is the closest to 70, but the exact midpoint is 70 — 6PM at 71 is nearest.
