In computing descriptive statistics from grouped data, data values are treated as if they occur at the midpoint of a class. This is a common estimation method used in statistics, and it allows for easier calculations and representations of data. The grouped data result may not necessarily be more accurate than an ungrouped result, as it depends on the specific situation and the level of detail needed. Grouped data computations can be used in both population and sample analysis.
