Granularity refers to the level of detail or precision in data collection and analysis. In the context of data, granularity determines how fine or coarse the data points are. A high level of granularity means data is collected with detailed, specific information, while a low level of granularity provides more general, aggregated data.
Granularity is important because it determines the depth of insights you can gain from the data. Finer granularity provides more detailed information, allowing businesses to make more specific and targeted decisions.
