A Meta-Analysis of the Relative Effects of Tabular and Graphic Display Formats on Decision-Making Performance

The results of 21 between-subjects experiments assessing the relative effects of tabular and graphic formats of data presentation on decision-making accu- racy were quantitatively reviewed using the meta-analysis procedure developed by Hunter, Schmidt, and Jackson (1982). Sampling error and differential range restriction accounted for variability in the average differences between tabular and graphic presentations, and there was no difference in the effects of the two presentation formats. These results counter recent assertions that task complexity moderates the effect of presentation format. The findings should also discourage further investigation of the effects of tabular and graphic formats using the conventional methodology.
