Cite a Startling Fact or Statistic

As you research your topic, take note of any information that defies your expectations or surprises you. If you have a strong reaction to something you learn, your audience may, too. When using a startling fact or statistic as an attention getter, it’s important to get the most bang for your buck. You can do this by sharing more than one fact or statistic that builds up the audience’s interest. When using numbers, it’s also good to repeat and/or repackage the statistics so they stick in the audience’s mind, which you can see in the following example:

In 1994, sixteen states reported that 15–19 percent of their population was considered obese. Every other state reported obesity rates less than that. In 2010, no states reported obesity rates in that same category of 15–19 percent, because every single state had at least a 20 percent obesity rate. In just six years, we went from no states with an obesity rate higher than 19 percent, to fifty. Currently, the national obesity rate for adults is nearly 34 percent. This dramatic rise in obesity is charted on the Center for Disease Control and Prevention’s website, and these rates are expected to continue to rise.

The speaker could have just started by stating that nearly 34 percent of the US adult population was obese in 2011. But statistics aren’t meaningful without context. So sharing how that number rose dramatically over six years helps the audience members see the trend and understand what the current number means. The fourth sentence repackages and summarizes the statistics mentioned in the first three sentences, which again sets up an interesting and informative contrast. Last, the speaker provides a verbal citation for the source of the statistic.
