back to [[Statistical Model]] There are different ways to study a unit and different names applied in different statistical disciplines. #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. #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). #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. ---- [[Dick Beldin]]
