Which of the following is NOT one of the four principles of dashboard design?

The principle that is not recognized among the well-established four principles of dashboard design is Effectivity. The four commonly accepted principles are Clarity, Efficiency, Balance, and Focus.

Clarity ensures that the information displayed is straightforward and easy to understand, avoiding any ambiguity that could confuse the viewer. Efficiency refers to the design's ability to present information quickly and actionably, allowing users to capture insights without unnecessary effort. Balance involves distributing visual elements in a way that looks organized and feels symmetrical, enhancing the overall aesthetics and usability of the dashboard.

Effectivity, although an important concept in various contexts, is not considered one of the foundational principles specifically used in dashboard design. This concept might be confused with other performance metrics or criteria used to evaluate outputs in different fields, but it does not directly apply when discussing the core principles of creating functional and effective dashboards.
