An example of descriptive data analysis is an hourly traffic report for a highway. Descriptive analytics refers to the analysis of historical data to gain insights and understand what has happened in the past. In this case, an hourly traffic report for a highway is an example of descriptive data analysis because it provides information about the current state of the system (i.e. the traffic on the highway) based on historical data. The report describes the traffic conditions and provides information about what has happened in the past hour.
