What is Statistics?
Statistics entails, amongst other, the study of data analysis methods. In laboratories, commercial institutions and factories data are collected on a daily basis. This data needs to be processed in order to extract useful information. Statistics supplies the techniques for this process and is very important for many fields of study and is increasingly essential.
So, what is statistics? Several informal definitions are offered in the book A Career in Statistics: Beyond the Numbers by Gerald Hahn and Necip Doganaksoy:
- 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 quintessential interdisciplinary science
- The art of telling a story with [numerical] data
