Answer 2

POPULATION PARAMETER(p) is a value used to represent a certain QUANTIFIABLE characteristic of a population. This is like the mean or variance of a population and often these values are unknown, and are estimated using sample data.

The Characteristics may be Relegion, Caste, Language, customs, People, s*x(Male/Female), Culture & traditions etc

For EXAMPLE, the population mean is a parameter that is often used to indicate the No of people Quantifiable to different Castes in a certain state.

Hope you are clear!

Answer 3

A parameter is a number computed from a population. Contrast this with the definition of a statistic. A parameter is a constant, unchanging value. There is no random variation in a parameter. If the size of the population is large (as is typically the case), then you may find that a parameter is difficult or even impossible to compute. An example of a parameter would be:

The average length of stay in the birth hospital for all infants born in the United States.
