What Is Population Parameter. Population parameters also termed population characteristics are numerical expressions summarizing various aspects of the entire population. Thus population parameter is a characteristic of population by which the natures of a population can be estimated. One common example is the population mean where F. Calculating Mean Variance and Standard Deviation on Population Data known to be a Population parameters.
This video explains what population parameters are. The descriptive inference may be model dependent or design based. A parameter is a fixed number because no randomness is involved. A parameter is to a population as a statistic is to a sample. Inferential statistics enables you to make an educated guess about a population parameter based on a statistic computed from a sample randomly drawn from that population see Figure 1. It is a type of interval estimate of a population parameter.

Inferential statistics enables you to make an educated guess about a population parameter based on a statistic computed from a sample randomly drawn from that population see Figure 1. Population parameter definition a quantity or statistical measure that for a given population is fixed and that is used as the value of a variable in some general distribution or frequency function to make it descriptive of that population. In fact parameter values are nearly always unknowable. To understand the nature of the population some quantitative measurements of the population are needed that is defined as population parameter. A confidence intervalestimate of a population parameter is a statement of bounds on that parameter and includes your level of confidence that the parameter actually falls within those bounds. Population parameters are numeric values calculated for a population which tell people about the characterstics related to the data and the shape of the curves.
