Statistics for Data Science 1 - W3_L3: Describing numerical data - median and mode

Welcome to Week 3 Lecture 3 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 explores two essential measures of central tendency — the median and the mode — and how they help describe the center of numerical data. You’ll learn how to calculate each measure, understand their properties, and see how they differ from the mean (average). The session also examines how the median and mode change when constants are added to or multiplied by data values. Practical demonstrations using Google Sheets show how to compute these measures and visualize them effectively. By the end of this lecture, you’ll have a clear understanding of when and how to use each measure to best represent your data.
