Editing Estimation theory (section)

== Examples ==
For example, it is desired to estimate the proportion of a population of voters who will vote for a particular candidate.  That proportion is the parameter sought; the estimate is based on a small random sample of voters. Alternatively, it is desired to estimate the probability of a voter voting for a particular candidate, based on some demographic features, such as age.

Or, for example, in [[radar]] the aim is to find the range of objects (airplanes, boats, etc.) by analyzing the two-way transit timing of received echoes of transmitted pulses. Since the reflected pulses are unavoidably embedded in electrical noise, their measured values are randomly distributed, so that the transit time must be estimated.

As another example, in electrical communication theory, the measurements which contain information regarding the parameters of interest are often associated with a [[noise (physics)|noisy]] [[signal (electrical engineering)|signal]].
