EA Graphics Interpretation 2 — Questions and Answers
Question 1: A stacked bar chart shows total project hours: Engineering=60%, Marketing=25%, Admin=15%, totaling 2,000 hours. How many hours are in Marketing?
- 500 (Correct answer)
- 300
- 400
- 600
Correct answer: 500
Marketing hours = 25% × 2,000 = 500 hours.
Question 2: A scatter plot has a cluster of points in the lower-left and one outlier in the upper-right. What effect does including the outlier have on the correlation coefficient?
- Decreases it toward zero.
- Increases it toward +1. (Correct answer)
- Has no effect.
- Makes it negative.
Correct answer: Increases it toward +1.
A single outlier in the upper-right strengthens the apparent positive correlation, pulling the coefficient closer to +1.
Question 3: A bar chart compares five products' profit margins: 12%, 8%, 15%, 10%, 6%. The company discontinues the lowest-margin product. What is the new average margin for the remaining four?
- 11.25% (Correct answer)
- 10%
- 10.5%
- 12%
Correct answer: 11.25%
Sum of remaining = 12 + 8 + 15 + 10 = 45; average = 45 / 4 = 11.25%.
Question 4: A line graph shows two products' sales over 5 years. They intersect at Year 3. What does the intersection point represent?
- Product A overtakes Product B in sales.
- Both products had equal sales in Year 3. (Correct answer)
- Year 3 was the peak sales year.
- Product B was discontinued in Year 3.
Correct answer: Both products had equal sales in Year 3.
An intersection on a line graph means both series had the same value at that point in time.
Question 5: A pie chart shows revenue by region. North America = 45%, Europe = 30%, Asia = 20%, Other = 5%. If the company targets increasing Asia to 30%, and total revenue stays at $600M, how much additional revenue is needed from Asia?
- $60M (Correct answer)
- $30M
- $90M
- $120M
Correct answer: $60M
Current Asia = 20% × $600M = $120M; target = 30% × $600M = $180M; additional = $60M.
Question 6: A graph shows a company's stock price over 12 months forming a U-shape. What pattern does this represent?
- Steady growth
- Initial decline followed by recovery (Correct answer)
- Consistent volatility
- A plateau
Correct answer: Initial decline followed by recovery
A U-shaped curve indicates the value fell initially and then recovered over the period shown.
