Quick Answer
The correct answer is to include a note that correlation does not imply causation. This is essential because a strong positive correlation between advertising spend and revenue only shows that the two variables move together, not that one causes the other. Without this caveat, stakeholders might mistakenly assume that increasing ad spend will always boost revenue, ignoring lurking variables like seasonality or market trends. On the CompTIA Data+ DA0-001 exam, this concept tests your ability to avoid misleading insights when interpreting scatter plots and regression outputs. A common trap is to confuse correlation with causation, especially when the relationship appears strong; the exam often presents a scenario where an analyst must explicitly state this limitation. Remember the memory tip: “Correlation is not causation—just because two things dance together doesn’t mean one is leading the dance.”
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.
A data analyst creates a scatter plot showing the relationship between advertising spend and revenue. The plot shows a strong positive correlation. Which of the following should the analyst include in the report to ensure accurate communication?
Include a note that correlation does not imply causation.
This prevents misinterpretation of the relationship.
Replace the scatter plot with a bar chart.
Why wrong: Bar chart is not appropriate for showing correlation.
Remove any outliers from the plot.
Why wrong: Removing outliers may distort the true relationship.
Add a trend line to the scatter plot.
Why wrong: A trend line is optional and does not address causation.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Include a note that correlation does not imply causation.
Option B is correct because correlation does not imply causation, and this caveat is essential. Option A is wrong because the scatter plot already shows the relationship. Option C is wrong because removing points could bias the analysis. Option D is wrong because a regression line is not necessary for every scatter plot.
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.
Include a note that correlation does not imply causation.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
Bar chart is not appropriate for showing correlation.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
