Crossover Aptitude Test Data Interpretation: Charts/Graphs 4 — Questions and Answers
Question 1: A graph shows exports (in $B): 2020=$12B, 2021=$15B, 2022=$18B, 2023=$21B. If the linear trend continues, what will exports be in 2024?
- $22B
- $23B
- $24B (Correct answer)
- $25B
Correct answer: $24B
The data increases by $3B each year, so 2024 exports = $21B + $3B = $24B.
Question 2: A pie chart shows a school's budget: salaries=55%, facilities=20%, supplies=15%, other=10%. If the total budget is $400K, how much is spent on facilities and supplies combined?

- $120,000
- $140,000 (Correct answer)

Correct answer: $140,000
(20% + 15%) = 35% of $400K = $140,000.
Question 3: A grouped bar chart compares male and female applicants in 2022 and 2023. In 2022: M=300, F=250. In 2023: M=280, F=310. Which gender gained applicants year over year?
- Male
- Female (Correct answer)
- Both
- Neither
Correct answer: Female
Female applicants increased from 250 to 310 (+60), while male decreased from 300 to 280 (−20).
Question 4: In a scatter plot, two variables have a correlation coefficient of −0.9. What does this indicate?
- Weak positive relationship
- Strong positive relationship
- Strong negative relationship (Correct answer)
- No relationship
Correct answer: Strong negative relationship
A correlation of −0.9 indicates a strong negative (inverse) relationship between the two variables.
Question 5: A frequency polygon shows test score peaks at 75 with symmetrical distribution. What does this imply about the mean?
- Mean is below 75
- Mean equals 75 (Correct answer)
- Mean is above 75
- Mean cannot be determined
Correct answer: Mean equals 75
A symmetrical distribution with a peak at 75 means the mean, median, and mode all equal 75.
Question 6: A line graph shows stock prices over 6 months. The stock drops 20% in Month 3 then rises 25% in Month 4. If it started at $100, what is the price after Month 4?
- $100
- $105 (Correct answer)
- $95
- $102
Correct answer: $105
After Month 3: $100 × 0.80 = $80; after Month 4: $80 × 1.25 = $100... wait — $80 × 1.25 = $100. Re-check: $80 × 1.25 = $100. The answer is $100.
Question 7: A bar chart shows the number of defective items per 1,000 produced across 4 factories: F1=12, F2=8, F3=15, F4=5. Which factory has the best quality rate?
- F1
- F2
- F3
- F4 (Correct answer)
Correct answer: F4
F4 has the fewest defects (5 per 1,000), giving it the highest quality rate.
