Geometric Mean | Measures of Central Tendency | CA Foundation | Chapter 14 Unit 1 | Lecture 2

LIVE LECTURE ALERT! Daily at a Fixed Time — Master CA Foundation Quantitative Aptitude! Welcome to Chapter 14: Measures of Central Tendency — Lecture 2: Geometric Mean! In this focused LIVE session, CA Anup Verma — experienced faculty for CA Foundation Quantitative Aptitude — takes you deep into Geometric Mean, one of the most mathematically elegant and exam-relevant measures of central tendency in the entire Statistics chapter. If you attended Lecture 1 on Arithmetic Mean, you already have the foundation. Now we build on it! Geometric Mean is NOT just a formula — it has powerful properties and special applications in business, finance, and index numbers that examiners LOVE to test! If you are preparing for CA Foundation Sep 2026 or onward exams, this lecture is designed EXACTLY for you! 🔥 SECTION 1: GEOMETRIC MEAN — CONCEPT & MEANING 1.
