The central limit theorem (CLT) says that as sample sizes grow higher, the distribution of sample means approaches a normal distribution, independent of the population's distribution. For the CLT to hold, sample sizes of 30 or more are frequently regarded sufficient.
The central limit theorem gives a formula for the sample mean and the sample standard deviation when the population mean and standard deviation are known. This is given as follows: Sample mean = Population mean = μ μ Sample standard deviation = (Population standard deviation) / √n = σ / √n.
To summarise, the central limit theorem has three different components:
A population is sampled repeatedly.
Increasing the size of the sample
The distribution of the population.
The Central Limit Theorem underpins what a data scientist does on a daily basis: making statistical judgments about data. Without having to take a fresh sample to compare it against, the theorem allows us to calculate the likelihood that our sample will diverge from the population.

great resource to learn data science in hindi. but in this particular video lecture there is a mistake....actually mutually exclusive event can never be independent event.
