Suksesna statistik praktis dumasar kana pokus problem definition. Sacara tipe, we seek to take action on some population, for example when a batch of material from production must be reléased to the customer or sentenced for scrap or rework. Alternatively, we seek knowledge about the cause system of which the population is an outcome, for example

when a reséarcher performs an experiment on rats with the intention of gaining insights into biochemistry that can be applied for the benefit of humans. In the latter case, the population of concern can be difficult to specify, as it is in the case of méasuring some physical characteristic such as the electrical conductivity of copper.

However, in all cases, time spent in making the population of concern precise is always well spent, often because it raises many issues, ambiguities and questions that would otherwise have been overlooked at this stage.
