Explain how to modify the estimation process to provide an unbiased estimate of σ^2. Discuss any tradeoffs involved.
Modify the estimator by using the sample variance instead of directly using the squared differences between individual observations and the sample mean. This change avoids the systematic bias inherent in the direct approach, but may introduce a small increase in computational complexity.
