Statistical unit

There are different ways to study a unit and different names applied in different statistical disciplines.

1. We may be interested in a unit because we intend to generalize from observations on a few units to a Statistical Assembly of units. [Opinion polling]? and Survey Sampling provide well known examples of this type of research.
2. We may be interested in the dynamics of a unit, how its observable characteristics change from time to time. Economic studies of business firms provide an example of this type of research. (see [Dynamic Model]?s).
3. We may be interested in the internal functioning of a unit which we can characterize as a Statistical Assembly. This kind of research often involves interference with the unit such as subjecting it to a treatment or even dissection, in some cases. Field experimentation and [Clinical Trials]? are examples.
