# What is inferential statistics?

We explain what inferential statistics is and its different uses. In addition, examples and descriptive statistics.

1. ### What is inferential statistics?

Inferential statistics or statistical inference is called the branch of Statistics responsible for making deductions , that is, inferring properties, conclusions and trends, from a sample of the set. Its role is to interpret, make projections and comparisons.

Inferential statistics usually employ mechanisms that allow you to carry out such deductions, such as point estimation tests (or confidence intervals), hypothesis tests, parametric tests (such as mean, difference of means, proportions, etc.) and not parametric (such as chi-square test, etc.). Also useful are correlation and regression analysis, chronological series, analysis of variance, among others.

Therefore, inferential statistics  is extremely useful in the analysis of populations and trends , to get a possible idea of ​​the actions and reactions of the same in the face of specific conditions. This does not mean that they can be predicted faithfully, nor that we are in the presence of an exact science, but of a possible approximation to the final result.
