Why do designers use tables to display data?

Designers often use tables to display data because they effectively organize and present individual figures that require a high level of precision. Tables allow for the clear display of values, making it easy for the viewer to compare specific data points directly. This is particularly valuable when the numerical data is intricate or detailed, as it allows the audience to read and interpret the figures without ambiguity.

In contrast, other options, while they serve different purposes, do not specifically address the primary function of tables in data presentation. Option A relates to visualizing changes over time, which is typically done using line graphs or bar charts that better illustrate trends rather than precise numerical data. Option C mentions the visual representation of shapes, which is more associated with diagrams and illustrations, and does not pertain to the presentation of tabulated data. Lastly, option D deals with promotional purposes, which generally involves visual marketing techniques rather than the structured presentation style that tables offer. Thus, the primary reason why designers opt for tables is to facilitate the direct display of precise individual figures.
