Two statistics display information specifically for grouped data:
Data groups – displays the number of data groups in the retrieval
Data grouped by – displays what the data is grouped by (anchor point, manual selection, traceability field, date/time period, etc.)
When a chart or report contains grouped data, the statistics for that chart or report (e.g., on a Statistics List) are calculated for all of the data in the retrieval— not only the most recent data group. To view statistics calculated for only one data group, see Viewing details for data groups.
