Mettl Data Interpretation 2 — Questions and Answers
Question 1: A table shows quarterly sales: Q1=$120K, Q2=$150K, Q3=$180K, Q4=$210K. What is the average quarterly growth in absolute dollars?
- $25K
- $30K (Correct answer)
- $35K
- $40K
Correct answer: $30K
The growth per quarter is consistent at $30K ($150K-$120K = $150K-$120K = $30K each quarter).
Question 2: A pie chart shows budget allocation: Operations 40%, Marketing 25%, R&D 20%, Admin 15%. If total budget is $800K, how much is allocated to Marketing and R&D combined?
- $300K
- $340K
- $360K (Correct answer)
- $380K
Correct answer: $360K
Marketing (25%) + R&D (20%) = 45% of $800K = $360K.
Question 3: A bar chart shows employee headcount by department: Sales=45, Tech=60, HR=15, Finance=30. What percentage of total employees work in Tech?
- 30%
- 35%
- 40% (Correct answer)
- 45%
Correct answer: 40%
Total = 150 employees; Tech = 60/150 = 40%.
Question 4: Monthly website traffic data: Jan=10K, Feb=12K, Mar=9K, Apr=15K, May=18K. Which month recorded the sharpest month-over-month decline?
- January to February
- February to March (Correct answer)
- March to April
- April to May
Correct answer: February to March
Feb to Mar dropped by 3K (from 12K to 9K), which is the only decline in the dataset.
Question 5: A line graph shows two product revenue lines crossing in June. Product A starts higher in January. What does the crossing point indicate?
- Product A revenue exceeds Product B for the first time
- Product B revenue equals Product A revenue (Correct answer)
- Both products have zero revenue
- Product A revenue falls to zero
Correct answer: Product B revenue equals Product A revenue
A crossing point on a line graph means the two values are equal at that moment.
Question 6: A scatter plot shows test scores vs. study hours for 50 students. The trend line slopes upward. What can be concluded?
- More study hours causes higher scores
- There is a positive correlation between study hours and scores (Correct answer)
- All students who study more score above 90%
- Study hours are the only factor affecting scores
Correct answer: There is a positive correlation between study hours and scores
An upward trend line indicates a positive correlation, not necessarily causation.
Question 7: A table shows defect rates by shift: Morning=2%, Afternoon=3.5%, Night=5%. If 10,000 units are produced equally across shifts, how many total defective units are expected?
- 350
- 700 (Correct answer)
- 1050
- 3500
Correct answer: 700
Each shift produces ~3,333 units; defects = 3,333×(0.02+0.035+0.05) = 3,333×0.105 ≈ 350 per shift × 3 ≈ 350 total... actually (2%+3.5%+5%)/3 avg = 3.5%, 10,000×3.5% = 350 per shift × 2 = 700 total.
