High granularity level refers to a high level of detail, vice-versa low granularity level refers to a low level of detail. Practically speaking, the more subdividable and specific a data is, the more granular it is considered to be.
Detailed explanation-3: -Data that has a low level of granularity would have a small number of individual pieces of information, such as summary data or aggregated data. The granularity of data can affect how it is used and analyzed, and can impact the accuracy and usefulness of the results.
