Be Prepared: Before the presentation, ensure you have thoroughly reviewed your data sources and methodologies. Know your numbers inside and out. Cite Sources: Clearly reference where your data comes from. Use reputable sources and be ready to provide documentation or links to the original data. Explain Methodology: Sometimes, data can be misinterpreted without proper context. Explain the relevance of the data and how it fits into the larger picture. If there are still doubts, offer to provide additional information or conduct further analysis after the meeting. Be Honest: If you discover an error in your data, acknowledge it promptly and explain how you will correct it. Honesty can build trust and credibility.

Have all the back up information for every single data you show in a presentation. Build a story behind the story, and you will earn their trust.
