A parameter is a descriptor, not necessarily numerical, and not restricted to descriptions of a population. But if we are talking about a population, let us say the population of the United States, we can break it down into males and females, or children and adults, or Repbulicans, Democrats, members of other parties or members of no parties, and we would be defiing parameters of gender, age, and political affiliation.

Parameter

adjective of quantity describe ''how much'' of a thing is meant.

A numerical adjective is placed before a noun to describe the noun. Examples:We bought a box of six donuts.One student earned an A.A numerical pronoun takes the place of a noun in a sentence. Examples: The donuts are six to a box.One of the students earned an A.

There are probably many probability distributions that have just one parameter. The most important one for statistical analysis is probably the Student t distribution.This probability distribution is fully described by a single parameter which is often called "degrees of freedom". The parameter describes the scale of the distribution, and not the location, since the Student t distribution is always centered at zero (unlike the normal distribution, which has a scale parameter, the variance, and a location parameter, the mean).Another example of a distribution that is described with a single parameter is the exponential distribution. Unlike the Student t distribution, it is a distribution that takes only positive values.

The characteristic or value of a population that is under consideration is called a parameter. It represents a specific aspect of the entire population and is often unknown and estimated using sample data. Parameters can include means, proportions, variances, and other measures that describe the population.

Demographic parameters are characteristics used to describe a population, such as age, gender, income, education level, and occupation. These parameters are used to segment populations for research or marketing purposes.

A numerical value used as a summary measure for a population of data is called a statistic. It helps to describe or understand the data more easily by providing a single value that represents the entire dataset.
