SAMPLE VARIANCE is NOT an Unbiased Estimator of Population Variance
*Thanks to Avik Da(my senior batchmate) for having made me understand this Proof!
**Welcome back all my ever sweet, generous and kind fellas!**
In this video, we have established proof in Statistics which states:-
SAMPLE VARIANCE is NOT an Unbiased Estimator of Population Variance
meaning, Sample Variance is a BIASED Estimate.
The formulas used here are:
1. Sample Variance
2. S^2 (this is actually the unbiased estimate of Population Variance)
Using S^2 we have shown Sample Variance isn't an Unbiased Estimate.
