About Mahalanobis


Mahalanobis attended the University of Cambridge, where he studied physics and mathematics.


Mahalanobis developed several practical mathematical and statistical methods, including the Mahalanobis distance, which he applied to India's social and economic problems, according to Britannica. The statistician's methods had a major role to play in India's industrialisation in the 1950s and 1960s. 


Mahalanobis found a method to calculate agricultural productivity using random sampling methods, and devised a technique to assess socioeconomic conditions.


He founded the Indian Statistical Institute in Calcutta in 1931. In 1950, he founded the National Sample Survey, and in 1951, the Central Statistical Organization. These are statistical agencies which perform the collection of government data. 


From 1955 to 1967, Mahalanobis served on the Planning Commission of India, and applied his mathematical reasoning to Indian industry.


Mahalanobis performed work in other fields such as physics, anthropology, meteorology and biology.


Mahalanobis served as the chairman of the United Nations Sub-Commission on Sampling from 1947 to 1951. In 1949, he was appointed the honourary statistical adviser to the government of India. The Indian government awarded him the Padma Vibhushan in 1968, for his contributions to statistics.
