Did you know?
In probability theory, the central limit theorem (CLT) establishes that, in many situations, for identically distributed independent samples, the standardized sample mean tends towards the standard normal distribution even if the original variables themselves are not normally distributed. The theorem is a key concept in probability theory because it implies that probabilistic and statistical methods that work for normal distributions can be applicable to many problems involvi… WebMay 3, 2024 · Central Limit Theorem Explained. The central limit theorem in statistics states that, given a sufficiently large sample size, the distribution of the sample mean for a variable will approximate a normal distribution regardless of that variable’s in the population distribution. Unpacking the meaning of that complex definition can be difficult.
