Consider these sentences:
The number of videos on Youtube is rising everyday
60 hours of video is uploaded on Youtube every minute

Statistics can make a presentation boring and mundane. But used in the right manner, statistics can make people sit up and take notice of what you are saying.

Choose your statistics with care so that they strengthen your argument and strike a chord with the audience. Practice it to achieve the desired effect when you present it. Voice, body language and the right tone are a few things to get right for the right impact.
