I'm thinking here about RU-vid rather than formal presentation... but I'm always impressed how "This Old Tony" manages to maintain engagement when all we can see of him is his gesturing hands.
This video is very helpful. Will you do a video about Q&A sessions of presentations in the future? What is the appropriate way to deliver answers, and what happens if you don't understand/don't know the answer to the question?
Ooh, great idea. Briefly: remember the points from the video: you are the boss of the room and there are only three kinds of questions. Deliver the answers you know with confidence, admit to not knowing the answers to impossible questions and interact well with the golden third kind. If someone questions your findings or data, don't take that as an attack but rather engage with the questioner. Often they've just misunderstood what you said; sometimes they just need a bit more information and sometimes (if you're lucky) they really have spotted a mistake/problem and that will help you lots in the future. If that's the case (it's not common but it does happen), then admit the mistake/problem with good grace and (usually) thank them for their help. As long as you've done the work, you'll be fine - and you'll know if you haven't done the work.
