This document provides guidance on creating effective PowerPoint presentations with 3 main points: 1. Structure slides clearly with a limited number of bullet points per slide, use headings to outline your presentation, and display points one at a time. 2. Use fonts sizes of 18 points or larger that contrast with the background, and keep formatting consistent throughout. 3. Include graphs and charts to visualize data trends, but keep them simple without unnecessary elements that could distract from the content.
