How are parameters and samples related in statistics?

A parameter is a characteristic of a population. A statistic is a characteristic of 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). Figure 1.Illustration of the relationship between samples

What is the value of the population parameter?

How are parameters fixed in a statistical procedure?

Definition. In other situations, parameters may be fixed by the nature of the sampling procedure used or the kind of statistical procedure being carried out (for example, the number of degrees of freedom in a Pearson’s chi-squared test ).

How is a random sample used in statistics?

In order to use statistics to learn things about the population, the sample must be random. A random sample is one in which every member of a population has an equal chance of being selected. The most commonly used sample is a simple random sample.
