When describing a time you used data to inform a decision, which elements should you include?

• A. The data sources and analysis method.
• B. Only the final result, with no data details.
• C. The data sources, analysis method, the decision taken, and the measurable outcome.
• D. Why you preferred a particular option regardless of data.

Answer: (C)

When you describe a time you used data to inform a decision, you want a complete, believable story that shows where the data came from, how you treated it, what you actually did, and what happened as a result. That means including four things: the data sources you used, the method or approach you applied to analyze the data, the decision you ultimately took based on that analysis, and the measurable outcome that followed. This combination demonstrates credibility, demonstrates your reasoning process, and proves the impact of your decision with concrete results.

Including only the data sources and analysis method misses what was decided and why it mattered. Focusing only on the final result omits how you reached it, which can leave the interviewer unsure about your reasoning. Describing why you preferred one option without tying it to the data ignores the evidence that supported your choice. By covering data sources, analysis method, decision, and measurable outcome, you provide a full, compelling picture of your data-driven decision-making process.
