Objects are the lists of specific items on which the calculation can be performed. Although the primary place for objects is the "Rows" pane, they can also be placed in the "Columns" pane (as split only) or used as a filter. In order to use an object, drag it and drop it in a proper pane. Alternatively, a left-click on the menu or right-click on the object name will open an object context menu, allowing you to add the object to any panes.
Objects can be nested one in the other or split by a regular question nested in it. Read more in Nesting.
It is possible for some objects to be used in more than one variant (if they are defined). The variants may differ, e.g., by the level of granularity.

Place selected objects in Rows to perform calculations on the level of the object.
