What is the purpose of a data dashboard in mitigating information overload?

• A. A data dashboard stores all data in a single file.
• B. A data dashboard is used to archive logs without visualization.
• C. It provides prioritized, at-a-glance views to support rapid decision-making.
• D. It replaces ISR data entirely.

Answer: (C)

Data dashboards reduce information overload by turning a flood of data into a clear, prioritized visual summary. They highlight the most important indicators and present them in an at-a-glance format, often with color cues and simple trends. This lets you quickly grasp current status, spot anomalies, and understand how things are moving, so you can make fast, informed decisions. You can usually drill down for deeper detail if needed, but the surface view stays concise and decision-oriented. The other options miss the primary function of dashboards: they are not just storage in one file, nor mere archives without visualization, and they do not replace the underlying data sources.
