# Statistics

## Welcome to the exciting world of Statistics!

### What is Statistics?

Statistics is the science that studies how knowledge is obtained from data. It involves the study of data analysis methods and techniques that help to extract useful information from data. Whether you are working in a laboratory, a commercial institution, or a factory, data is being collected and processed on a daily basis. Statistics provides the tools necessary to interpret this data and make sense of it.

In the book "A Career in Statistics: Beyond the Numbers" by Gerald Hahn and Necip Doganaksoy, several informal definitions of statistics are offered:

• The science of learning from (or making sense out of) data.
• The theory and methods of extracting information from observational data for solving real-world problems.
• The science of uncertainty.
• The quintessential interdisciplinary science.
• The art of telling a story with numerical data.
