Question

Write a paragraph or more to explain what the central limit theorem is and what it is used for in statistics?

Answer 1

according to central limit theorem for large sample size, sampling distribution is approximately normal with meanand standard deviation √n

where is standard deviation of population and is mean of population.

central limit theorem says that almost all distribution approaches to normal distribution if sample size is large. for making easy calculation we approximate distribution to normal distribution through central limit theorem.
