Effectively concluding your PowerPoint slides can mean the difference between a mediocre presentation and an exceptional one. Although you want to avoid merely summarising your presentation, it is important that you reiterate your main points to the audience, as well as leave them with an engaging thought or quote to consider. Your conclusion is your final chance to make a lasting impression on your listeners.
Bring your presentation full circle. Answer any questions you may not have answered throughout the rest of the presentation and explain to your audience why the presentation as a whole matters. Answer the question "So what?" Ask yourself this question as you write your conclusion and be sure to provide an answer. If you don't have an answer for it, neither will your audience.
Direct your audience to further information or research. Give them ways to get involved or places to look if they want to know more about the subject of your presentation. Let the audience know that they have a choice about whether they do something with the information you've provided them.
End with a strong quote. Make sure it is relevant to your presentation, and be sure to credit the person who said it.
Provoke your audience. Use any relevant data to make your point. Back up any claims you might have made in your presentation with statistical proof. Show your audience that you have done your research.
Make a prediction. Consider the information you have provided throughout your presentation and make a projection about what will happen should things continue the way they are or what could happen if they change. Again, support these claims with statistics or any other relevant data.
Avoid clichés. Do not give any information you cannot support.
