Statistic vs parameter examples. Below are some more example of parameters and statistics. Suppose we study the population of dogs in Kansas City. A parameter of this population would be the mean height of all dogs in the city.
A statistic would be the mean height of 50 of these dogs. A statistic is a number that describes some characteristic of a sample. A parameter is a number that describes some characteristic of a population.

The parameter is a fixed measure which describes the target population. 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 1Illustration of the relationship between samples and populations. In a survey of a sample of high school students 43 said that their mother has taught them the most about managing money.

This stats video tutorial explains the difference between a statistic and a parameter. It also discusses the difference between the population and sample. In simple words statistics vs Parameter a parameter is a characteristic of the population.
