The Observer XT - Organizing event data at different hierarchical levels

Observational data are usually organized in discrete elements of varying complexity. In many cases it is important to relate data to variables that represent the context in which the observation takes place, for example the temperature of the room or the age of the subjects. Several of these variables may have different values in the same context, for example different subjects interacting in a room may have different ages. It is therefore important to relate data to such variables defined at different hierarchical levels. The Observer XT offers this possibility by linking subjects and multiple data sets to specific independent variables.
