本研究藉由探討近年來常在大眾媒體、社群網絡間用於闡述新議題之相關數據時,經常作為數據呈現工具的資料視覺化與視覺資訊圖表於說服力及洞見提供效果之不同,進而確立針對不同背景之使用族群下,兩種數據呈現方式的使用時機。本研究框架建立於闡述使用者接收訊息後透過不同的處理路徑進而產生態度改變和說服效果的訊息處理論之一:思辨可能模式。本研究利用中華民國教育部所提供之國內大專校院畢業生就業薪資數據集透過資料視覺化與視覺資訊圖表兩種實驗媒介。實驗過程中受測者將隨機閱讀其中一種數據呈現形式並回答一系列涵蓋個人偏好,透過此數據呈現所獲得的洞見與態度上的轉變之問項。 實驗結果指出,閱讀資料視覺化之受測者較閱讀視覺資訊圖表之受測者普遍有較佳的洞見發現。然而受測者年齡也與洞見發現的效果有所影響。雖然近年圖表設計師等製作者較多傾向於利用視覺吸引較為豐富的視覺資訊圖表提高對議題涉入程度低之族群的參與度,本研究之實驗結果指出即便是議題涉入低族群,在資料視覺化中所獲得的洞見也較視覺資訊圖表佳。另一方面,在說服效果中,資料視覺化與視覺資訊圖表對涉入族群高低之族群所造成之影響雖相似,對議題有較高之涉入族群卻較易被說服。此外,實驗結果亦發現視覺呈現之品質及視覺吸引度也會提升數據呈現之說服效果。
The study investigates when to use data visualizations and when to use infographics, by comparing the two information charts for viewer insight and persuasion. Furthermore, this study explores how viewer involvement differs between data visualization and infographic. We used a research framework based on Elaboration Likelihood Model, which is an information processing theory that described how high and low involvement participants process information. We designed an experiment with treatments based on a dataset of starting salaries provided by Ministry of Education. In the experiment, participants were exposed to one of the treatments — data visualization or infographic — then asked to answer a variety of questions about perceptions, insight, and opinion change. The results show that data visualization is overall better at insight. However, participants’ age also influenced results. Although practitioners design infographics to engage low involvement viewers, our study found that even low involvement participants have better insight from data visualizations than infographics. On the other hand, the persuasiveness of the data visualization and infographic was similar between high and low involvement participants. The high involvement group was more easily persuaded. Furthermore, argument quality and attractiveness also increased persuasiveness.
