Central Limit Theorem

Central Limit Theorem. So far, we have been working on discrete and continuous random variables. But most of the time, we deal with ONE random variable at a time. For example, if a random variable X follows a normal distribution, then ……. How about we have more than one random variable?

The Central Limit Theorem

The Central Limit Theorem. The Central Limit Theorem tells us that for a population with any distribution, the distribution of the sample mean approaches a normal distribution as the sample size increases.

The Central Limit Theorem

The Central Limit Theorem. For simple random samples from any population with finite mean and variance, as n becomes increasingly large, the sampling distribution of the sample means is approximately normally distributed. The Central Limit Theorem.
