‘Greetings from Hiroshima, Japan, the City of Peace. I would like to express my sincere appreciation to all of
you for celebrating the World Statistics Day on October 20, 2010 at Ramjas College.
….. Here at the Radiation Effects Research Foundation, formerly known as the Atomic Bomb Casualty
Commission, we are dedicated to promote and we have a legacy of, the collection and statistical analyses of
the data on the survivors of Hiroshima and Nagasaki Bombings for peaceful purposes and for the betterment
of the society at large. This is what I view as “Statistics for Peace”. Mahatma Gandhi, as a staunch believer of
peace and a practitioner of Ahimsa -- the principle of nonviolence, took an oath to work for peace and
always speak the truth. Following his example, on this World Statistics Day, we as statisticians, must promise
ourselves to do so through our data and honest scientific data analyses. By virtue of our professional
abilities, we have the immense power to extract truth from numbers and we must sincerely strive to utilize
this special ability to make this world a peaceful and better place in which to live. If we all could do so, that
is what our “statistical significance” will be in its truest sense.
I wish you all a joyous and intellectually stimulating World Statistics Day and my best wishes to the
organizers for a successful symposium.’

‘Greetings!
It is a well-known fact that the public activity and discourse of both governments and
other (public or private) organizations are necessarily base on data and the resulting
(statistical) conclusions or inferences affect all activities in some way. To make
meaningful summary and both immediate as well as long range predictions based on
this data and analysis, we need to proceed generally in three parts: (i) formulating a
model, (ii) collecting data to verify the model's suitability, and (iii) a prognosis or
prediction. The first one is based on an appropriate but necessary mathematical
construct, the second one is the statistical analysis, and the final one leading to
predictions both for the short and long ranges. The situation is to be continuously
refined, updated and analyzed. This is the fundamental statistical activity which is
necessarily based on suitable mathematical formulation, and relevant statistical
estimation (of parameters), testing (both these termed `inference methodology') and
then prediction. It is thus clear that the three aspects noted above with statistical
analysis at the center, are the life blood of human activity, and thus it is important and
appropriate to celebrate this matter all over the world, reminding everyone about its
key role in governing as well as other human works. I therefore wish a grand success of
the organization of WSD at your place and all the future times.’

Statistics Day.
The UN declaration of a World Statistics day (WSD) gives all statisticians and Statistics a
valuable opportunity to contribute to our societies. Statistics can play a significant role
in the economic and social developments of our societies. We need to work towards
Evidence Based Policy in our governments and other organizations. This involves
Statistical Capacity Building efforts to improve the national Statistical Capacity. We
need to concentrate on improvements in Statistical Literacy in the society as a whole
and in particular in the school systems starting from Kintergarten. Let us hope that

‘Dear Dignitaries, guests, colleagues and students,
Much as I would have liked to, I am unable to attend the meeting to celebrate the World Statistics
Day at Ramjas College, as I am currently out of the country. I am writing this message to share my
thoughts for the occasion.
Use of probabilistic and statistical methods, to supplement deterministic reasoning,
to make sense of the complex realities that one encounters in various contexts is a major step in
the progress of mankind. We are now increasingly able to deduce dependable conclusions in a
scientific way, rather than depending on hunches, when only partial or sample inputs are
available from which we need insights about a broader set-up. The recent decades have
witnessed remarkable applications of the theme in various spheres of life. As we proceed, the
methods may be expected to be further perfected and ever more applications to be found. It is a
matter of great pleasure to note that India has played a pioneering role in the rise of the subject
and has been at the forefront in its applications.
This is a wonderful occasion to celebrate the achievements of this new form of knowledge
generation. I would like to compliment Ramjas College for organizing such an event for the
international World Statistics Day. I send my best wishes for the deliberations, both on my own
behalf and on behalf of the National Board for Higher Mathematics, which has endeavored to
support Probability and Statistics along with other streams of mathematics.’

‘I am very glad to know that the Department of Mathematics & Statistics, Ramjas
College, University of Delhi, is celebrating the First World Statistics Day on October 20

received a number of communications from ISI. They highlight the programs and have
made your Dept. visible all over world. It is a proud moment for all of us. I am indeed
very happy that you have taken the lead in this country on celebrating the WSD.
As we all know, the United Nations Statistical Department has declared, for the first
time, October 20, 2010 as World Statistics Day and gave a call to the national
governments to celebrate the many achievements of official statistics and to
strengthen the awareness and trust of the public in cooperation with national
statistical services. The International Statistical Institute is launching a new ISI
Declaration on Professional Ethics to be presented during a special session on this day
at the IAOS Conference in Santiago in Chile. In a broader context, however, we need to
ponder over and discuss how statistics has been serving the different sectors of
science & technology as well as helping in economic development at the national and
international levels during the past decades and how it should shape its role in future.
It is now well recognized that statistics has made inroads in almost every activity of the
society. Whether one is concerned with scientific experimentation or conducting large
scale sample surveys or gallop polls or concerns with dynamics of agricultural and

socio-economic development or sports or management & decision making or industrial
product development etc., one cannot escape statistical issues involved therein. In fact
everyone is interested in ascertaining the true picture of the phenomenon in his field
and it is the power of statistics that helps in extracting the truth from the data. Users
of statistics, however, do not fully comprehend the inherent statistical mechanism and
need necessary help from statisticians. There is a need therefore to develop awareness
about statistical concepts, in layman’s language, to the public at large. Just as we talk
of computer literacy these days, we need to stress statistics literacy as well. This
particular Day can be a proper time to launch plans and programs to this end.
I have no doubt, with the two-day comprehensive schedule chalked out by the
organizers, particularly by Professor Man Mohan Gupta and his colleagues, the event
would be an excellent treat to all concerned.
I convey my very best wishes to one and all for the success of this Convergence 2010

Aside from any other reasons, the linkage between the world of Actuarial Science and
the academic discipline of Statistics is strong enough for me to be part of the event. If I
look back at about 300 years of the world of actuarial science in its organized form as a
scientific discipline, I find that many of illustrious men of actuarial science were indeed
men of Statistics and Probability.
