Chapter 4: Developing and Supporting Your Ideas

# Testimony

### Statistics

How you present the statistical data in your presentation is important as well (Allen and Preis 125-31; Baesler and Burgoon 584-92). The following tips will make your use of statistics easier for your audience to understand and remember.

Relying on statistics alone lessens your chances of reaching all of your listeners. While statistical data can validate many of your ideas, your listeners want to hear more than numbers. Including some human-interest stories and relevant testimony makes your speech more interesting and highlights the human factor that many audience members need in order to be persuaded. If you rely solely on statistical data to support your main points, you will most likely fail to reach an entire subgroup of the audience.

Incorporating your statistics into charts, graphs, and tables makes it easier for your audience to visualize the numbers that you quote. Remember the old adage, “A picture is worth a thousand words. ” Colorful, well-designed charts and graphs can give your audience an immediate understanding of the data that you include in your presentation. In essence, graphs, charts, and tables provide your audience with a snapshot of your data.

### Stories/Illustrations

As mentioned above, statistics often need to be combined with other types of supporting material to reach those audience members who crave the human connection within a topic. Telling a story is a surprisingly easy way to connect to an audience; listeners love to hear a good story. Many of us can recall how much we enjoyed having stories read to us or told to us as children, so a speaker who can successfully incorporate stories and illustrations into her/his presentation usually finds a receptive audience. Sharing a funny story about your first disastrous attempt to cook easily leads into a speech titled “Fajitas Without the Hassle. ” The story serves to introduce you to the audience and sets the tone for your presentation. One could imagine that the speech that follows this story would include simple steps and cooking tips that anyone could master.

Certainly, humorous stories can arouse interest and work as a quick and effective attention-getter, but not all stories serve the same purpose or arouse the same feelings. Telling the story of a dying boy’s last wish could help you explain the work of the Make-A-Wish Foundation or your reasons for volunteering in the pediatric ward of your local hospital. The story helps your audience understand your reasons for volunteering or the need for more volunteers. Because this story is poignant and heartfelt, it is also likely to touch emotions and persuade your audience to listen -and perhaps volunteer too. While statistics revealing the number of children hospitalized because of fatal illnesses is valid information in such a speech, the human connection the audience gains from the story will probably make a greater impact.

### Definitions

The final support that we’d like to discuss is the use of definitions. Definitions are necessary in many presentations -especially those that introduce new information to listeners or those that explain a complicated process or concept. One of the biggest mistakes that new speakers make is to assume that audience members already have an adequate understanding of the concept or process being discussed in their presentations. Providing the definition of necessary terms makes the new information accessible to your listeners.

There are several online resources available to you for this purpose. You might visit Dictionary. com or Merriam-Webster.com. You can also look up the definition of most words through search engines, such as Ask.com or Bing.com. Adequate audience analysis perhaps through the use of a questionnaire or an informal survey should help you pinpoint your audience’s prior knowledge of your subject. If you suspect that your listeners have little prior knowledge, one of your basic goals must be to include clear supporting information and to define the terms you use throughout your speech. Failure to do so will result in listeners who have lost interest in your subject or who have become frustrated with you as a speaker.

An excessive use of jargon can also hinder your audience’s understanding of your presentation. Workers in most organizations use a specialized lingo or abbreviated language understood almost exclusively by the employees of that workplace. This language code is a form of shorthand that makes communication within the organization succinct, to the point, and often private. Military men and women use abbreviations and acronyms that most of us cannot possibly understand. Doctors, nurses, and other medical personnel utilize a coded language that few outside the hospital or office walls could decipher. Workplace jargon meets the needs of its members, but it is important to keep in mind that the jargon is relatively obscure to those outside of the workplace. If you must use jargon in your speech, you’ll want to limit the frequency of its use to ensure that you can readily explain it to your listeners.

As you can see, the supporting material that you choose will vary, depending on the personal preferences of the speaker, the goal of the presentation, the topic, and the analysis of the audience. As is true in most situations, the more variety that you can include within your speech, the more your audience is likely to find your presentation interesting, relevant, and appealing. Researching to find the most effective supporting material is crucial.
