Скачать или смотреть 10.21 Bessel’s Correction | Why n-1 in sample variance? | Statistics in Hindi

In this video, we explore why we divide by (n–1) instead of n when calculating sample variance. You’ll understand the intuition behind Bessel’s Correction, how it removes bias in estimating population variance, and why it gives a more accurate measure of data spread.

📌 Topics Covered in this Video:
1. Population vs Sample Variance – Explained Intuitively
2. Limitation of calculating variance using n
3. Introduction to Bessel’s Correction – Why do we need it?
4. Why we use (n–1) instead of n for computing sample variance
5. How Bessel’s Correction ensures an unbiased estimate of population variance
