Statistics are used in a variety of ways.Sep 26, 2020 · A sample space is the set of all possible outcomes of a statistical experiment, and it is sometimes referred to as a probability space. And outcomes are observations of the experiment, and they are sometimes referred to as sample points. An event is a subset of a sample space as discussed by Shafer and Zhang.

The sample is a small portion of that population. Because of the large volume of data in the population, it raises the computational cost. The availability of all data points in the population is also an issue. In short: We calculate the statistics using the sample. Using these sample statistics, we make conclusions about the population. 22.
