The Situation of Finite Populations

Sample Size Estimation

Statistical inference is the process by which we acquire information about populations from samples.

There are two types of inference:

Estimation

Hypotheses testing

The objective of estimation is to determine the value of a population parameter on the basis of a sample statistic.

There are two types of estimators:

Point Estimator

Interval estimator

A point estimator draws inference about a population by estimating the value of an unknown parameter using a single value or point.

An interval estimator draws inferences about a population by estimating the value of an unknown parameter using an interval.
