A collection of slides used for a presentation should have what common characteristic?

A collection of slides used for a presentation should have a uniform design to ensure coherence and consistency throughout the presentation. This characteristic allows the audience to focus on the content being presented rather than being distracted by varying styles or formats. A uniform design typically includes consistent use of colors, fonts, layouts, and visual elements, which helps maintain a professional appearance and enhances the overall communication of the message. When slides are uniform, it conveys a sense of organization and credibility, making it easier for the audience to follow along and retain information.
