# Inferential Statistics

Get introduced to sampling methods and terms.

**Inferential statistics** is a branch of statistics that makes inferences or predictions about a population based on a sample. In inferential statistics, we use models, formulas, and other varied methods to make estimates, predictions, and generalizations about a population. Using these methods, we can estimate population parameters, find confidence intervals, conduct hypothesis tests, and compare samples.

## Population and sample

**Population** refers to all the individuals or elements we are interested in for a particular statistical study. All people living in a country are an example of a population.
