EDPT Data Interpretation and Table Reading 3 — Questions and Answers
Question 1: A production table shows daily unit output per worker: A=45, B=38, C=52, D=41. What is the average output per worker?
- 42 units
- 44 units (Correct answer)
- 45 units
- 48 units
Correct answer: 44 units
(45 + 38 + 52 + 41) / 4 = 176 / 4 = 44 units per worker.
Question 2: A table lists typing speeds (WPM) for six employees: 65, 72, 58, 80, 74, 67. What is the mode of this data set?
- 65 WPM
- 67 WPM
- 72 WPM
- There is no mode (Correct answer)
Correct answer: There is no mode
Each value appears exactly once in the data set, so there is no mode.
Question 3: A defect log shows items per batch of 50: Batch 1=3, Batch 2=5, Batch 3=2, Batch 4=4, Batch 5=6. If the acceptable defect limit is 10% (5 items), which batch exceeds the limit?
- Batch 4 only
- Batch 5 only (Correct answer)
- Batches 4 and 5
- Batches 2 and 5
Correct answer: Batch 5 only
10% of 50 = 5 defects maximum; only Batch 5 with 6 defects exceeds that limit.
Question 4: A regional sales table shows: North=800 units, South=400 units, East=600 units, West=200 units. What is the ratio of North region sales to West region sales?
- 2:1
- 3:1

Correct answer: 4:1
North : West = 800 : 200 = 4 : 1.
Question 5: A bank rate table shows: Bank A=3.5%, Bank B=4.2%, Bank C=3.8%, Bank D=4.0%. How much more annual interest would a $5,000 deposit earn at Bank B versus Bank A?

- $40
- $45
Correct answer: $35
Bank B: $5,000 × 0.042 = $210; Bank A: $5,000 × 0.035 = $175; difference = $35.
Question 6: A task log shows completion times (minutes): Task 1=12, Task 2=18, Task 3=15, Task 4=20, Task 5=10. If the total deadline is 90 minutes, how much time remains after all tasks are complete?
- 5 minutes
- 10 minutes
- 15 minutes (Correct answer)
- 20 minutes
Correct answer: 15 minutes
Total task time = 12+18+15+20+10 = 75 minutes; remaining = 90 − 75 = 15 minutes.
