[Audio] INTRODUCTION OF STATISTICS Statistics is a branch of mathematics and science that deals with the collection, analysis, interpretation, and presentation of data. It plays a crucial role in making sense of complex information and making informed decisions. Statistics is used in various fields such as science, business, economics, social sciences, and more. Key concepts in statistics include data types, measures of central tendency, variability, probability, hypothesis testing, and regression analysis. It provides the tools and techniques to summarize, explore, and draw conclusions from data, making it an essential part of modern decision-making and research.

[Audio] INDIAN STATISTICIAN Prasanta Chandra Mahalanobis Prasanta Chandra Mahalanobis (1893-1972) was a pioneering Indian statistician and founder of the Indian Statistical Institute (ISI) in 1931. His contributions to statistics and its application were vast and influential. He introduced the Mahalanobis distance, a key concept in multivariate statistics, and played a vital role in promoting sample surveys as a tool for data-driven decision-making. Mahalanobis was a key architect of India's economic planning, influencing policies through data and statistics, and he played a crucial role in the establishment of the Planning Commission of India. His extensive anthropometric surveys contributed to understanding the health and nutrition of India's population. Prasanta Chandra Mahalanobis' work left an enduring legacy, shaping the field of statistics and significantly impacting India's development and planning efforts..

[Audio] INDIAN STATISTICIAN P. V. Sukhatme PestonjiVakil Sukhatme (1911-1997) was a prominent Indian statistician known for his significant contributions to agricultural statistics and experimental design. He played a crucial role in advancing statistical methodologies to improve agricultural practices in India. Sukhatme's work focused on the design and analysis of agricultural experiments, aiming to enhance crop yields and agricultural productivity. His research and publications had a lasting impact on the field of agricultural statistics and contributed to the development of more efficient and sustainable farming practices in India..

[Audio] FOREIGN STATISTICIAN Sir Ronald Aylmer Fisher (1890-1962), a distinguished British statistician, geneticist, and biologist, made profound contributions to the fields of statistics and genetics. He is renowned for developing fundamental statistical techniques, including the analysis of variance (ANOVA), which allows for the partitioning of data variation and is integral to experimental design and hypothesis testing. Fisher was a pioneer in the design of experiments, emphasizing randomization and laying the groundwork for modern experimental design principles. He contributed significantly to the method of maximum likelihood estimation, a fundamental concept in statistics. In genetics, Fisher's work greatly advanced the understanding of genetic variation and parameter estimation. His creation of Fisher's exact test remains a vital statistical tool for assessing associations in contingency tables. Fisher's exceptional contributions have left an enduring legacy, making him one of the most influential statisticians and scientists of the 20th century..

[Audio] FOREIGN STATISTICIAN George E. P. Box George Edward Pelham Box (1919-2013) was a renowned British statistician known for his significant contributions to the field of statistical methodology, particularly in the areas of time series analysis and experimental design. He is best known for developing the Box-Jenkins methodology, which has become a standard for time series analysis in statistics, and the Box-Cox transformation used for data transformation and stabilization in statistical modeling. His work had a profound impact on the field of applied statistics, and his innovative approaches are widely used in various fields to model and analyze complex data. George E. P. Box's contributions continue to be highly influential in the practice of statistics and data analysis..

[Audio] CONCLUSION In conclusion, the four statisticians mentioned—C.R. Rao, Prasanta Chandra Mahalanobis, Sir Ronald A. Fisher, and George E. P. Box—have made substantial and lasting contributions to the field of statistics. C.R. Rao's work has been influential in various statistical areas, including multivariate analysis. Prasanta Chandra Mahalanobis played a vital role in establishing the Indian Statistical Institute and promoting statistical methods in India's development. Sir Ronald A. Fisher's pioneering work in analysis of variance and genetics has had a profound and enduring impact. George E. P. Box's innovative approaches in time series analysis and experimental design continue to shape the practice of statistics. Each of these statisticians has left an indelible mark on the field, advancing statistical theory and applications..
