Official statistics are statistics published by government agencies or other public bodies such as international organizations as a public good. They provide quantitative or qualitative information on all major areas of citizens' lives, such as economic and social development, living conditions, health, education, and the environment.
However, the major disadvantage in using statistical mean is that it can be affected by extreme values in the data set and therefore be biased. The statistical mean is widely used not only in the fields of mathematics and statistics, but also in economics, sociology and history. It gives important information about a data set and provides insight into the experiment and nature of the data.
