Creating More Effective Graphs
Presented : Thursday, March 23, 2006
Speakers: Dr. Naomi Robbins, NBR and Michael O'Connell,
Insightful Corporation
This webcast uses before and after figures
to demonstrate that the choice of a graph form has a profound
effect on the reader's understanding of the data. The
before figures are commonly used graphs from a variety
of fields including marketing, survey results, and engineering.
They include stacked, grouped and divided bar charts;
multiple line charts; radar plots, and other common graph
forms. Many of the after figures make use of Trellis
Graphics. No statistical background is needed to understand
the presentation. The webcast clearly shows the power
of Trellis Graphics.
