Abstract
Communicating data without some measure of their precision can lead to misinterpretation and incorrect inferences. Several conventions for displaying error along with the data they modify are described and illustrated. Alternatives are offered that seem to provide improvements in the effective communication of error as well as increasing their ease, and hence their likelihood, of use. These alternatives are illustrated principally with data from the National Assessment of Educational Progress.Keywords
