Revelian Test Data Interpretation Skills 4 — Questions and Answers
Question 1: A company's revenue was $4.5M last year and is projected to grow 12% this year. What is the projected revenue?
- $5.04M (Correct answer)
- $5.14M
- $4.95M
- $5.24M
Correct answer: $5.04M
$4.5M × 1.12 = $5.04M.
Question 2: A two-column table shows hours worked and units produced for 5 workers. Worker E produced 48 units in 6 hours while others averaged 7 units/hour. How does Worker E compare?
- Worker E is below the average productivity rate (Correct answer)
- Worker E is above the average productivity rate
- Worker E matches the average productivity rate
- Cannot be determined
Correct answer: Worker E is below the average productivity rate
Worker E's rate = 48/6 = 8 units/hour, which is above the group average of 7 units/hour.
Question 3: A bar chart shows quarterly profits: Q1=$30K, Q2=$45K, Q3=$40K, Q4=$55K. By what percentage did profit increase from Q1 to Q4?
- 83.3% (Correct answer)
- 75%
- 66.7%
- 90%
Correct answer: 83.3%
(55−30)/30 × 100 = 25/30 × 100 ≈ 83.3%.
Question 4: A pie chart shows expense categories: Salaries 55%, Rent 20%, Utilities 10%, Supplies 8%, Other 7%. Which two categories together equal exactly the Salaries portion?
- Rent and Utilities and Supplies (38%) — none equal 55% exactly
- Rent and Other
- Utilities and Supplies and Other (Correct answer)
- Rent and Supplies
Correct answer: Utilities and Supplies and Other
Utilities (10%) + Supplies (8%) + Other (7%) = 25%, while no two-category combo equals 55%; the closest full answer is Utilities+Supplies+Other = 25% which does not equal 55%, making all pairs incorrect — Rent+Utilities+Supplies = 38% is still wrong, so none match 55%.
Question 5: A table shows customer satisfaction scores (out of 10) across five products: 7.2, 8.5, 6.9, 8.5, 7.4. What is the mode of these scores?
- 8.5 (Correct answer)
- 7.2
- 7.4
- 6.9
Correct answer: 8.5
8.5 appears twice while all other values appear once, making it the mode.
Question 6: A graph shows that sales drop sharply every December and peak every June over a 3-year period. What analytical term best describes this pattern?
- Seasonality (Correct answer)
- Outlier
- Trend
- Correlation
Correct answer: Seasonality
Predictable, repeating fluctuations tied to calendar periods are called seasonality.
Question 7: A data set has a mean of 50 and a standard deviation of 5. A data point of 65 is recorded. How many standard deviations above the mean is this value?
- 3 (Correct answer)
- 2
- 4
- 1.5
Correct answer: 3
(65 − 50) / 5 = 15/5 = 3 standard deviations above the mean.
