Quick Answer
The answer is Home & Garden, which achieved a 50% increase from $20,000 to $30,000. This is determined by applying the formula for calculating percentage increase: subtract the 2023 value from the 2024 value, divide that difference by the 2023 value, then multiply by 100. For Home & Garden, the calculation is ($30,000 - $20,000) / $20,000 * 100 = 50%, which outpaces Clothing’s 25%, Books’ 33.3%, and Electronics’ 40%. On the CompTIA Data+ DA0-001 exam, this type of question tests your ability to compute and compare relative growth rates, often using a table or chart of year-over-year data. A common trap is to compare absolute dollar increases instead of percentages—here, Electronics had the largest absolute jump ($10,000), but its percentage increase was lower because it started from a higher base. To remember, think “new minus old, divided by old, times one hundred,” and always check the starting value to avoid the base effect trap.
This DA0-001 practice question tests your understanding of communicating data insights. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. The data shows sales by product category for two years. Which product category had the highest percentage increase from 2023 to 2024?
Clothing
Why wrong: Clothing sales decreased, so no increase.
Books
Why wrong: Books increased only 5%.
Electronics
Why wrong: Electronics increased 12.5%, which is less than Home & Garden's 15.79%.
Home & Garden
Home & Garden had the highest percentage increase of about 15.8%.

Correct answer & explanation
Home & Garden
Home & Garden had the highest percentage increase from 2023 to 2024 because its sales grew from $20,000 to $30,000, a 50% increase, which is greater than the percentage increases for Clothing (25%), Books (33.3%), and Electronics (40%). The percentage change is calculated as ((2024 value - 2023 value) / 2023 value) * 100, and Home & Garden yields the highest result.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Clothing

Clothing sales decreased, so no increase.
Books
Why it's wrong here
Books increased only 5%.
Electronics
Why it's wrong here
Electronics increased 12.5%, which is less than Home & Garden's 15.79%.
Home & Garden
Why this is correct
Home & Garden had the highest percentage increase of about 15.8%.

Common exam traps
CompTIA often tests the distinction between absolute increase and percentage increase, leading candidates to mistakenly choose Clothing because it has the largest absolute dollar increase ($10,000), while the question asks for the highest percentage increase.
Detailed technical explanation
Percentage increase is a relative measure that normalizes growth by the base value, making it essential for comparing categories with different starting points. In data analysis, using absolute differences (e.g., $10,000 for both Clothing and Home & Garden) can be misleading; percentage change reveals that Home & Garden's growth was proportionally larger. This concept is fundamental in business intelligence tools like Tableau or Power BI when calculating year-over-year growth metrics.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
