The law of large numbers has a very central role in probability and statistics. It states that if you repeat an experiment independently a large number of times and average the result, what you obtain should be close to the expected value. There are two main versions of the law of large numbers. They are called the weak and strong laws of the large numbers. The difference between them is

Watch video · The law of large numbers just says that if we take a sample of n observations of our random variable, and if we were to average all of those observations– and let me define another variable. Let’s call that x sub n with a line on top of it. This is the mean of n observations of our random variable. So it’s literally this is my first observation. So you can kind of say I run the experiment
The weak and strong laws of large numbers Jordan Bell jordan.bell@gmail.com Department of Mathematics, University of Toronto May 29, 2015 1 Introduction Using Egorov’s theorem, one proves that if a sequence of random variables X n converges almost surely to a random variable X then X n converges in probability to X.1 Let X nbe a sequence of L1 random variables, n 1.

THE LAW OF LARGE NUMBERS THEOREM (The Law of Large Numbers) Actually the LLN above is the “weak” law of large numbers. There is also a “strong” law of large numbers, which implies the weak law. Understanding the statement of the SLLN involves higher math, so we will skip it. 2. Created Date : 1/21/2004 8:45:00 PM

And this is what the weak law of large numbers tells us. So in some vague sense, it tells us that the sample means, when you take the average of many, many measurements in your sample, then the sample mean is a good estimate of the true mean in the sense that it approaches the true mean as your …
