On June 29th, every year, India observes National Statistics Day to honour the exceptional contributions made by Professor Prasanta Chandra Mahalanobis in the fields of statistics and economic planning. This significant day commemorates Mahalanobis’ birth anniversary and serves as a reminder of the crucial role that statistics play in shaping policies, decision-making, and national development. Join us as we explore the history of National Statistics Day, dive into Mahalanobis’ life and achievements, and highlight the importance of statistics in today’s world.

National Statistics Day: A Tribute to Prasanta Chandra Mahalanobis:

National Statistics Day was established by the Government of India in 2006 to pay tribute to Prasanta Chandra Mahalanobis and his invaluable contributions to the field of statistics.
