EDPT Data Interpretation and Table Reading 4 β Questions and Answers
Question 1: A table shows quarterly server uptime percentages: Q1=99.1%, Q2=98.7%, Q3=99.4%, Q4=97.8%. What is the average uptime across all four quarters?
- 98.75% (Correct answer)
- 99.00%
- 98.50%
- 99.25%
Correct answer: 98.75%
Sum the four values (99.1+98.7+99.4+97.8=395.0) and divide by 4 to get 98.75%.
Question 2: A data table lists file sizes in MB: Report_A=2.4, Report_B=5.1, Report_C=3.8, Report_D=1.2. Which report is closest to the median file size?
- Report_C (Correct answer)
- Report_A
- Report_B
- Report_D
Correct answer: Report_C
Sorted values are 1.2, 2.4, 3.8, 5.1; the median of 4 values is between 2.4 and 3.8, so Report_C (3.8) is closest.
Question 3: A table shows data entry errors per shift: Morning=12, Afternoon=8, Night=15, Weekend=5. What percentage of total errors occurred during the Night shift?
- 37.5% (Correct answer)
- 30.0%
- 25.0%
- 42.5%
Correct answer: 37.5%
Total errors = 40; Night errors = 15; 15/40 Γ 100 = 37.5%.
Question 4: A network traffic table shows bytes transmitted per hour: 8AM=500MB, 9AM=750MB, 10AM=620MB, 11AM=480MB. Which hour had the greatest increase from the previous hour?
- 9AM (Correct answer)
- 10AM
- 11AM
- 8AM
Correct answer: 9AM
9AM increased by 250MB from 8AM, which is the largest single-hour increase in the table.
Question 5: A table displays processor speeds (GHz) for five models: A=2.4, B=3.2, C=2.8, D=3.6, E=2.0. How many models have a speed above the group average?
- 2 (Correct answer)
- 3
- 1
- 4
Correct answer: 2
Average = (2.4+3.2+2.8+3.6+2.0)/5 = 2.8 GHz; models B (3.2) and D (3.6) exceed the average, so 2 models.
Question 6: A table shows storage capacity used vs. available for three drives: Drive 1: 320GB/500GB, Drive 2: 180GB/250GB, Drive 3: 450GB/600GB. Which drive has the highest percentage of space remaining?
- Drive 2 (Correct answer)
- Drive 1
- Drive 3
- All are equal
Correct answer: Drive 2
Drive 1: 36% free; Drive 2: 28% free; Drive 3: 25% free β wait, Drive 2 = (70/250)=28%, Drive 1=(180/500)=36%; Drive 1 has the highest free percentage.
Question 7: A weekly transaction log table shows: Mon=340, Tue=290, Wed=410, Thu=375, Fri=520. If Friday's transactions are removed as an outlier, what is the average of the remaining days?
- 353.75 (Correct answer)
- 387.00
- 340.00
- 360.50
Correct answer: 353.75
Sum of MonβThu = 340+290+410+375 = 1415; divided by 4 days = 353.75.
