If you're invited to speak to a women's or men's organization, you know the answer to this question at once. Quite often, however, audiences are mixed fairly evenly, although at times one sex may predominate.

Do members of your prospective audience spend evenings watching TV movies and drinking beer at a local tavern, or do they read the Harvard Classics and attend concerts of Beethoven and Mozart? Do they play bingo and 21, or do they pursue the questions the intriguing intricacies of contract bridge and chess? Answers to these questions can help you choose the most appropriate material and language for your audience. Your choices can be crucial in determining the success or failure of your presentation.

Are the members recent college graduates, senior citizens, or business executives in midcareer? Just remember, age exerts a powerful impact on people's attitudes, values and motivations.

For example, your department manager may ask you to explain and demonstrate a procedure to some fellow employee. Or she may select you to address your department on behalf of the local blood donor drive. In both speech situations—in class and on the job—you're familiar with your audience; you speak their language; you have things in common with them.

Are you aware of the educational background of your audience? How many of them have doctoral degrees, master degrees or bachelor degrees? This will decide what kind of language you should adopt and how much they can understand.

Are the members of the organization interested in the topic or are they required to attend regardless of their interest? If the latter is true, what types of material will most likely pique their curiosity?
