• You can use this as case study and examples

Mahalanobis’s strategy in handling large-scale data

• Tackling Big Data: Mahalanobis encountered a Big Data challenge when his large-scale surveys yielded substantial amounts of data that required effective analysis for planning purposes. He successfully persuaded the government to procure the country’s first two digital computers in 1956 and 1958 for the Indian Statistical Institute. This accomplishment marked the introduction of computers and their utilization in handling vast amounts of data in India.
• Embracing Technology: Mahalanobis embraced technology throughout his career. He built simple machines to facilitate surveys and measurements, displaying a keen interest in leveraging technology for data collection and analysis. His adoption of digital computers showcases his progressive approach to incorporating technological advancements into statistical practices.
• Mathematical Calculations: Mahalanobis’s strategy involved employing complex mathematical calculations to tackle the extensive data generated from surveys. By utilizing digital computers, he aimed to streamline and expedite the process of analyzing large-scale datasets, enabling effective planning and decision-making.
• Built-in Cross-Checks: Mahalanobis was inspired by Kautilya’s Arthashastra and introduced the concept of built-in cross-checks in his surveys. This approach aimed to ensure data accuracy and reliability, minimizing errors and contradictions in the collected data. These cross-checks were implemented to enhance the quality control of statistical analysis and maintain the integrity of the findings.
