Correct responses were added together to get a total accuracy score for each subject. Prior to viewing the presentation material, subjects were asked to provide demographic information and were tested for color blindness. Subjects were randomly selected for each group. In the current experiment 3 out of 50 males were color blind. An analysis of variance was done to determine if a significant difference existed with the accuracy of graphs versus tabular charts.
Tabular charts result in significantly higher scores than pie, line, and bar charts.
An analysis of variance was done in order to determine if a significant difference existed between the accuracy of bar, line, and pie charts. This suggests that patterns neither deter or enhance extraction ability. The basic findings from the current experiment suggest that information extraction performance is dependent on presentation form and the task at hand. The current experiment showed that it took significantly longer to extract information from tables than graphical charts. The current experiment showed that tabular charts produce more accurate results than graphs.
