The Usefulness of a Map with Geographic Text: A Reanalysis of Experimental Data

Abstract

One research report of the usefulness of a map with geographic text appeared inconsistent with other research findings related to other graphic illustrations accompanying printed narrative. Consequently, data employed in the earlier report were reanalyzed through the use of analysis of covariance, a more powerful statistical procedure than the univariate analysis originally used. Results of this reanalysis revealed no treatment effects; that is, a map with text seemed not to be a superior condition to that of text alone. Research procedures as well as the substantive findings are discussed.
