Statistics for Data Science 1 - W3_L2: Describing numerical data - mean

Welcome to Week 3 Lecture 2 of the course "Statistics for Data Science - I" by Prof. Andrew Thangaraj. Full Course: https://study.iitm.ac.in/ds/course_pages/BSMA1002.html Video Overview This lecture provides a detailed introduction to summarizing numerical data using measures of central tendency, with a primary focus on the mean. You’ll learn the definition and interpretation of the mean for both sample and population data, along with its computation for ungrouped and grouped datasets. The session also demonstrates how the mean changes when a constant value is added to or multiplied with each data point, illustrating its mathematical properties and applications. By the end of this lecture, you will have a clear understanding of how to calculate and interpret the mean in various statistical contexts.
