There are many types of examples that a presenter can use to help an audience better understand a topic and the key points of a presentation. These include specific situations, problems, or stories designed to help illustrate a principle, method, or phenomenon. They are useful because they can make an abstract concept more concrete for an audience by providing a specific case. There are three main types of examples: brief, extended, and hypothetical.
Brief examples are used to further illustrate a point that may not be immediately obvious to all audience members but is not so complex that is requires a more lengthy example. Brief examples can be used by the presenter as an aside or on its own. A presenter may use a brief example in a presentation on politics in explaining the Electoral College. Since many people are familiar with how the Electoral College works, the presenter may just mention that the Electoral College is based on population and a brief example of how it is used to determine an election. In this situation it would not be necessary for a presented to go into a lengthy explanation of the process of the Electoral College since many people are familiar with the process.
Extended examples are used when a presenter is discussing a more complicated topic that they think their audience may be unfamiliar with. In an extended example a speaker may want to use a chart, graph, or other visual aid to help the audience understand the example. An instance in which an extended example could be used includes a presentation in which a speaker is explaining how the “time value of money” principle works in finance. Since this is a concept that people unfamiliar with finance may not immediately understand, a speaker will want to use an equation and other visual aids to further help the audience understand this principle. An extended example will likely take more time to explain than a brief example and will be about a more complex topic.
A hypothetical example is a fictional example that can be used when a speaker is explaining a complicated topic that makes the most sense when it is put into more realistic or relatable terms. For instance, if a presenter is discussing statistical probability, instead of explaining probability in terms of equations, it may make more sense for the presenter to make up a hypothetical example. This could be a story about a girl, Annie, picking 10 pieces of candy from a bag of 50 pieces of candy in which half are blue and half are red and then determining Annie’s probability of pulling out 10 total pieces of red candy. A hypothetical example helps the audience to better visualize a topic and relate to the point of the presentation more effectively.
Examples help the audience understand the key points; they should be to the point and complement the topic. One method of effectively communicating examples is by using an example to clarify and complement a main point of a presentation. Examples are essential to help an audience better understand a topic. However, a speaker should be careful to not overuse examples as too many examples may confuse the audience and distract them from focusing on the key points that the speaker is making.
