Population parameters or population characteristics can be estimated by taking representative samples of a population. In other words, conclusions about an entire population can be inferred from a sampling of that population. This sampling of the population can then be examined, and inferences made about the general population it represents. Various measures provide different types of data or measurements of data from which conclusions can be derived. Examples of these measures are Measures of Central Tendency and Measures of Dispersion.
