Rao’s ‎Centurychr(chr(chr('39') 39chr('39')) 39chr(chr('39') 39chr('39'))) chr (chr(chr('39') 39chr('39')) 39chr(chr('39')39chr('39'))) ‎, which has been scripted as a perception of an appreciation  note by involvements of  Bradley Efron, Shun-ichi Amari, Donald B. Rubin, Arni S. R. Srinivasa Rao and David R. Cox. Therefore, it is not possible to address this manuscript as a scientific paper, which is regularly accepted among the researchers. Evidently, the proposed translated article is prepared with the focus on appreciating professor Rao’s a century contribution in statistics. With this intention, Persian speakers, i.e., those who are somehow associated with statistics, could become aware of professor Rao’s invaluable role in spreading the statistics around the world. Absolutely, individuals that have achieved a bachelor’s degree in statistics, are familiar with at least two well-known titles:“Cramer-Rao’s inequalitychr (chr(chr('39')39chr('39')) 39chr(chr('39')39chr('39'))) chr(chr(chr('39') 39chr('39')) 39chr(chr('39') 39chr ('39'))) and “Rao-Blackwell theoremchr(chr(chr('39')39chr('39')) 39chr(chr('39')39chr('39')))chr(chr(chr('39')39chr('39')) 39chr(chr ('39')39chr('39'))) , possessing Rao’s designation in both titles. Needless to say, that mentioning his remarkable role in statistics and learning more about his outstanding character by some renowned statisticians, who have also made remarkable impacts on statistics, is a must. In accordance with the author of this paper, advantageous activities of Rao, some of which have come to this paper, can be considered as a model for those who enter in various fields of statistics and intend to follow Rao’s scientific and social life.
