Arithmetic Mean | Video #2 | Ch 8 | CBSE | Class 11 | Statistics | BBA, B.Com, CA Foundation, IBDP

Heylooo bacchooo! 👋😄 Welcome to Video 2 of Chapter 8 – Statistics (Class 11 Economics) on Measures of Central Tendency (MCT). In this video, we move deeper into Arithmetic Mean (AM) and cover the most important numerical and application-based concepts asked in exams. 📊🔥 🔁 Quick Recap of Video 1 (Part 1) In Video 1, we built the foundation by discussing: ✔ Meaning of Central Tendency (CT) ✔ Types of Averages (ToA) ✔ Objectives of Averages (OoA) ✔ Requisites of a Good Measure of Central Tendency (RGMCT) ✔ Arithmetic Mean (AM) — meaning and types ✔ AM under Individual Series (IS) — • Direct Method (DM) • Short-Cut Method (SCM) • Step-Deviation Method (SDM) ✔ AM under Discrete Series (DS) — • Direct Method (DM) • Short-Cut Method (SCM) • Step-Deviation Method (SDM) This gave you full conceptual clarity of basic averages and series. 📘 TOPICS COVERED IN THIS VIDEO (VIDEO 2) 8️⃣ Arithmetic Mean (AM) under Continuous Series (CS) We calculate AM using three methods: ✔ Direct Method (DM) ✔ Short-Cut Method (SCM) ✔ Step-Deviation Method (SDM) We explain class intervals, mid-values (xi), frequency (f), and why SDM saves time in large calculations. 9️⃣ Missing Value (MV) Problems Learn how to find missing frequencies or missing observations using the AM formula. This is a high-scoring and frequently asked numerical topic. 🔟 AM under Special Cases (5 Cases) We discuss important special situations such as: ✔ Cumulative Frequency Distribution ✔ Mid Value Series ✔ Inclusive Class Interval Series ✔ Open End Series ✔ Unequal Class interval Series These cases help you solve tricky questions confidently. 🚀 COMING NEXT – VIDEO 3 (Part 3) In the next video, we complete Arithmetic Mean (AM) with advanced theory + applications: 1️⃣1️⃣ Properties of Arithmetic Mean (PAM) 1️⃣2️⃣ Combined Mean (CM) 1️⃣3️⃣ Corrected Mean (CorM) 1️⃣4️⃣ Merits & Demerits of Arithmetic Mean (M&D of AM) 1️⃣5️⃣ Weighted Mean (WM) These topics are very important for theory questions and HOTS Numericals.
