It can be called the quantile function representation. 2R Dh@ker, Lecturer, PCNMS The word statistics comes from the Italian words Statista ( Statement). We report these formulae below. Deﬁnition 1.2.1. 1. If you’re a business major, you’re familiar with the role statistics plays in your field. It also deals with STATISTICS Statistics is concerned with scientific methods for ◦ collecting, ◦ organising, ◦ summarising, ◦ presenting and analysing data ◦ as well as deriving valid conclusions and making reasonable decisions on the basis of this analysis. For this reason, generating functions are very useful in analyzing discrete problems involving sequences of numbers or sequences of functions.
