Written Report Elements • Introduction • Executive Summary • Response Summary Questionnaire • Project Overview • Body Content • Narrative Description of Results • Tabular Listings of Numeric Data • Graphic Portrayal of Relationships • Conclusion • Summary of Main Findings • Recommendations to Client • Technical Appendix
Report Introduction: Executive Summary • Limit it to one or two pages • Use bullets or very brief paragraphs • Use headings to identify sections • Strive to excite interest in findings
Report Introduction: Project Overview • Highlight main information needs • Outline sampling and data collection • Briefly describe response outcomes
Report Introduction:Response Summary • Use a blank questionnaire • Strip out superfluous content • Insert percentages or averages
Narrative Body Text:Organization • Divide body content into sections • Use headings to identify sections • Describe the purpose of each section • List most important information first • Text references should precede tables
Narrative Body Text:Narrative Style • Use short, simple, direct sentences • Too little is better than too much • It’s better to be terse than rambling • Avoid technical jargon or buzz-words • Use nouns and limit use of pronouns • Strive to write as you would speak
Composing Report Tables • Number or letter them consecutively • Do not use Roman numerals • The title should say what’s in the body • Label all rows, columns, and sections clearly • Use conventional, standard formats • Use space and position to show relationships • List similar data in rows, columns, or sections
Composing Report Tables • Leave ample “white space”—avoid crowding • Indicate statistical significance with footnotes • Use vertical, not horizontal pages if possible • Make each one as self-explanatory as you can • Be sure they’re clean, simple, and uncluttered • Test them on someone to see if they’re clear • Include them after text reference, not before
Creating Charts and Graphs • Number or letter all types of figures consecutively • Create and use a standard format for similar figures • Titles should indicate what bars or lines represent • Use major and minor grid lines to show values • Use tic labels on the major grid lines to show values • Add value labels if quantities aren’t shown by locations • Indicate significance with superscripts and footnotes
Creating Charts and Graphs • Size figures to fit on vertical, not horizontal pages • Make each figure as self-explanatory as possible • Make figures clean, simple with ample white space • Include depth, shadow, or color only if it won’t detract • Have someone examine them to be sure they’re clear • Include figures after the text reference if possible
