Knowing your audience will help you prepare a presentation that will keep their attention and be useful to them.

As you plan your presentation, think about what types of things the audience will want to learn about, or how your presentation can share information in the best way.

Different audiences tend to learn information in different ways, so thinking about who your audience is can change how you share the information in your presentation.

For example, a group of accountants might be comfortable learning information by looking at a table of numbers. But people who aren't as good at math may prefer a brief oral summary of what the numbers mean.

You'll also need to think about how much the audience already knows about the topic of the presentation. This way, you can avoid spending time presenting information they already know.

It's always a good idea to avoid using slang or language that's too casual in a presentation, but a presentation to a group of friends can be more casual than a presentation to teachers or co-workers.
