🎯 Key Takeaways for quick navigation: 00:00 📚 Introduction to Consistent Estimators - Consistent estimators are a key property in statistics. - They aim to reduce variance in estimations. - This video discusses the concept of consistent estimators and their importance. 02:32 🎯 Definition of Consistent Estimator - A consistent estimator is one where, as the sample size grows, it converges to the true parameter in probability. - It's crucial for large sample sizes but not guaranteed for smaller ones. - The video explains the definition and its importance. 06:14 📈 Proving Sample Mean as a Consistent Estimator - Sample mean (x-bar) is shown to be a consistent estimator for the population mean (mu). - The proof is based on the Chebyshev inequality. - It demonstrates the properties required for a consistent estimator. 08:06 📊 Linear Combinations of Consistent Estimators - If t1 and t2 are consistent estimators of gamma1 and gamma2, a linear combination of them (at and bt) is also a consistent estimator. - The linearity property of consistent estimators is discussed. - This helps in understanding how to create new consistent estimators from existing ones. 10:00 💡 Bernoulli Distribution and Consistent Estimation - The sample mean of a Bernoulli distribution is proven to be a consistent estimator of the Bernoulli parameter (p). - The proof is shown by analyzing the mean and variance of the sample. - It highlights the concept of using the binomial distribution in such cases.

at 7:37 in video var(x bar)=1/n^2[var(x1)+var(x2)+....var(xn)] so how you have written 1/n^2
