Using Graphics to Report Evaluation Results

This guide provides detailed information on how to use graphics to represent data in evaluation reports.

 "People 'consume' information in different ways and presenting information graphically can help clarify evaluation results. While some find text easy to digest, others find that graphics - bar charts, pie charts, illustrations and photographs - can simplify complex information, emphasize key points and create a picture of data.

Graphics can also tell a story, showing proportions, comparisons, trends, geographic and technical data and, in the case of photographs, putting a 'human face' on a project.

This booklet gives a brief overview of how to choose among common types of graphics and ensure that they accurately represent your data." (Minter & Michaud, 2003)
