Master the Statistical Foundations of Data Science with R

In the world of data science, the ability to extract meaningful insights from raw data is paramount. While modern machine learning grabs headlines, the classical statistical methods of sampling theory and regression analysis remain the bedrock of reliable data analysis. The NPTEL course, "Essentials of Data Science With R Software-2: Sampling Theory and Linear Regression Analysis," bridges this crucial gap, teaching you how to apply these fundamental tools using the powerful, free R statistical software.

Taught by the renowned Prof. Shalabh from IIT Kanpur, this 12-week program is designed to provide a deep, practical understanding of how statistics drives data science, moving from theoretical concepts to hands-on implementation.

About the Course Instructor: Prof. Shalabh

Learning from an expert with both academic excellence and practical teaching experience is invaluable. Prof. Shalabh brings over 25 years of experience in teaching and research at IIT Kanpur. His expertise in linear models and regression analysis is globally recognized, evidenced by his seminal book co-authored with the legendary statistician Prof. C.R. Rao.

He is a pioneer in propagating R software in India, having developed widely accessed MOOC courses on NPTEL. His book, "Introduction to Statistics and Data Analysis With Exercises, Solutions and Applications in R," has been downloaded over 5.4 million times, a testament to his ability to demystify complex topics for a global audience.
