EDPT Data Interpretation and Table Reading 5

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?

Accepted Answer

1.8

Answer

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?

Accepted Answer

32%

Answer

(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?

Accepted Answer

Batch 4 and Batch 5

Answer

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?

Accepted Answer

3/8

Answer

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?

Accepted Answer

User

Answer

Admin failure rate = 2/50 = 4%; User failure rate = 18/330 ≈ 5.5%; Users have the higher failure rate.
