How to Prepare for Questions During a Scientific Presentation

You can prepare for questions by anticipating what an audience will ask, rehearsing short answers, and having a plan for questions you cannot answer. Questions are an opportunity to show understanding and to get feedback.

Anticipate likely questions

• Design and bias: Why this design? How did you handle confounding?
• Population and generalisability: Who was included? Does it apply to other groups?
• Measurement: How was the outcome defined and measured?
• Statistics: Why this analysis? What about missing data and multiple comparisons?
• Clinical meaning: Is the effect clinically important?
• Next steps: What would you do next?

Ask colleagues to question you in rehearsal and write down every question that arises.

A simple response framework

1. Listen to the whole question and pause.
2. Rephrase it briefly if unclear.
3. Answer directly in one to three sentences; link to evidence.
4. Acknowledge limits honestly where relevant.
5. Invite follow-up if time permits.

Difficult situations

• You do not know: say so, offer what you do know, and offer to follow up later.
• Hostile or lengthy comments: stay polite, answer the part that is a question and thank them.
• Question outside your data: state that your study did not address it and refer to what is known.

Illustrative example

Invented for teaching. Someone asks whether results hold in patients over 85. The speaker answers, "We had 40 patients over 85, too few for a separate analysis; the direction was similar, but the interval was wide, so I would not draw conclusions for that group."

After the session

Write down the questions you were asked and how you answered. Note any you could not answer and find the evidence afterwards; send a brief follow-up to the person who asked if you promised to do so. These notes help you improve the manuscript, strengthen your limitations section and prepare better for the next presentation.

Common pitfalls

• Defensiveness.
• Guessing instead of acknowledging uncertainty.

Key takeaways

• Rehearse questions, answer directly and be honest about limits.
• Thank the questioner.
