How do you present a data analysis to non-technical stakeholders?

What the interviewer wants to hear

• Start with the answer and recommendation
• Use simple language and one clear chart per point
• Show uncertainty honestly
• Link findings to business impact and next steps

Model answer

I start with the conclusion, not the method. For example: "Delivery delays are the main reason for the drop in repeat orders, and fixing the evening peak could recover about 4% of revenue." Then I support it with two or three simple charts, each making one point with a clear title. I avoid jargon like p-values and instead say "we are fairly confident the effect is between 2% and 6%". I am honest about limits, such as data gaps or the fact that it is a correlation, not a proven cause. I connect everything to what the audience cares about, like revenue, cost or customer experience, and end with a clear recommendation and next steps. I keep detailed methods in an appendix for anyone who wants to check the work.
