Statistics is a branch of applied mathematics concerned with the collection, description, analysis, and inference of conclusions from numerical data. The mathematical theories of statistics make extensive use of differential and integral calculus, probability theory, and linear algebra. The ability to make appropriate conclusions about large groups and general occurrences from the actions and other visible traits of small samples is of particular importance to statisticians. These tiny samples represent a subset of a broader group or a limited number of similar occurrences.

Describing the characteristics of samples and populations using descriptive statistics and inferential statistics, respectively, are two of the most important fields of statistics.

#### Salient Features of Statistics

- Statistics is the study and data manipulation, which includes methods for data collection, examination, analysis, and conclusion.
- Descriptive and inferential statistics are the two main types of statistics.
- Statistics can help you make better business and investment choices.

#### Uses of Statistics

Statistics are commonly employed in a variety of applications and occupations. Statistics are created whenever data is collected and examined. This can include everything from government organizations to academic research to financial analysis.

Economists gather and analyze a wide range of data, housing starts, including consumer spending, GDP growth, and inflation. Analysts and investors in finance gather information on businesses, industries, sentiment, and market price and volume data. The use of inferential statistics in various domains is referred to as econometrics. Statistical inference is used in a number of major financial models, including CAPM, Modern Portfolio Theory (MPT), and the Black-Scholes options pricing model.
