Therefore, various countries’ curricula and standards in mathematics require students to have the ability to judge statistical data visualizations and to be able to identify misleading data displays (e.g., National Council of Teachers of Mathematics, 2000). However, graphical features can create a distorting visual impression and mislead the reader.

It may be that the routines for the interpretation of pictures differ considerably depending on whether a person must calculate a quantity arithmetically or is prompted to estimate the quantity based on visual perception. This result deviates from research that found an overgeneralization of linearity when students compare the areas of two mathematically similar shapes. The experiment showed that, on average, a model assuming a quadratic relationship fitted best. Instead, it was analyzed which functional relationship between scale factor and estimated quantity best described people’s interpretation of pictorial charts. Therefore, the students’ answers were not rated as correct or incorrect.

The study aimed to evaluate how individuals perceive the quantities in the pictorial charts intuitively. In the present study, 63 university students answered a 12-item questionnaire containing three different pictorial charts. They represent different quantities with differently scaled pictures. Pictorial charts are a popular form of data visualization in media. This brief research report presents an experiment investigating how people interpret quantities displayed in pictorial charts.
