The results reveal that regardless of the self-rated assurance of the users, no significant difference in the effectiveness of task completions using visualizations could be registered. Furthermore the participants indicate in the questionnaire that using visualization their individual satisfaction level had no significant differences when compared to the users’ self-assurance levels. This indicates even users feeling not confident in interacting with computer systems they may feel confident in interacting with visualizations.
