The process of making inferences, based on sample data, about the numerical value of a population parameter.
A set of techniques where the value of a population parameter is inferred from sample data.
Estimation is the process by which sample data are used to indicate the value of an unknown quantity in a population. Results of estimation can be expressed as a single value, known as a point estimate; or a range of values, known as a confidence interval.
The process of using information from a sample to draw conclusions about the values of parameters in a population.
Estimation is concerned with inference about the numerical value of unknown population values from incomplete data, such as a sample. If a single figure is calculated for each unknown parameter, the process is called point estimation. If an interval is calculated within which the parameter is likely, in some sense, to lie, the process is called interval estimation.
