Presentation skill is essential for a data analyst to get our analysis across clearly and effectively. Many people including myself, feel terrified when asked to talk in public, especially to bigger groups. However, these fears can be reduced by good preparation. Presentation skills can be improved with a bit of work. And this blog is designed to help us with a step-by-step guide to putting together and delivering a professional and effective presentation.


Planning your presentation

Planning is the most important part of making a successful presentation. Before starting to build your content, make sure that you:

  2. Determine timing and purpose
  3. Identify relevant facts and a maximum of 3 key points
  4. Think through possible questions, including difficult ones
  5. Determine the most effective approach to engage participants 
  6. Choose a presentation method based on your presentation’s objective 
Building your presentation

Irrespective of whether your presentation is formal or informal, you should always aim to give a clear, well-structured delivery. To do so, you need to organize your presentation material to:

  1. Create a compelling opening, a central message, and a memorable closing
  2. Select appropriate presentation aids that help explain your key points
  3. Ensure the visual ads are well-designed and readable

Always rehearse your presentation by re-reading your notes and checking any equipment you’ll be using.


Delivering your presentation

There are several aspects to delivering your presentation on the day:

  1. Prepare the room by checking lighting, noise level and temperature, as well as any equipment you’ll need

  3. Use verbal skills appropriately to clearly articulate your message
  4. Be aware of nonverbal skills, and avoid distracting behaviours
  5. Invite and answer questions professionally during Q&A

However, there is no one good way to do a talk. The most memorable talks offer something fresh, something no one has seen before. So do not on any account try to emulate every piece of advice I’ve offered here. But make the talk your own. You know what’s distinctive about you and your idea. Play to your strengths and give a talk.
