Answer of MBA 103- Statistics for Management Assignment Question 1- Give the meaning of the word Statistics. Mention the characteristics of Statistics.

AnswerThe word "Statistics" which comes from latin word status, meaning a political state, originally meant information useful to the state, for example, information about the sizes of population
and armed forces. But this word has now acquired different meanings.

The word statistics refers to "numerical facts systematically arranged". In this sense, the word statistics is always used in the plural. We have, for instance, statistics of prices, statistics of road, accidents, statistics of crimes, statistics of births, statistics of educational institutions, etc. In all these examples, the word statistics denotes a set of numerical data in the respective fields.

For example, in measuring the length of screws, an accuracy of up to a millimetre may be required, whereas while measuring the heights of students in a class, an accuracy of up to a centimetre is enough.
