Order is important. Start with a statement of your purpose for writing. Add the when, who, how, and where details that you have organized into some rational order. Say what you think about the above, and end with a summary. Put endless tables of data in an appendix.
Straight text looks formidable.
Because we humans have relatively limited capacities for information processing, you should present your information in bite-sized chunks, which your reader may then quickly note and take in. The shorter, the more irresistible your paragraphs are. Put key ideas in indented paragraphs where they will be noticed. Just as you noticed this paragraph. Look for opportunities to use numbered or bulleted lists.
