12 Questions
What does the central limit theorem (CLT) state?
The distribution of a normalized sample mean converges to a standard normal distribution.
Why is the central limit theorem (CLT) considered a key concept in probability theory?
It implies that probabilistic methods for normal distributions can be extended to other types of distributions.
When was the modern general form of the central limit theorem (CLT) precisely stated?
1920
Which type of variables need to be normally distributed for the central limit theorem (CLT) to hold?
Neither original variables nor sample mean
What is the main implication of the central limit theorem (CLT) on statistical methods?
Statistical methods for normal distributions can be applied to many other types of distributions.
Which version of the central limit theorem (CLT) serves as a bridge between classical and modern probability theory?
Modern general form from 1920
What does the central limit theorem state about the probability distribution of observed averages?
It approximates a normal distribution
In the classical central limit theorem, what does the difference between the sample average and its limit approximate?
Normal distribution with mean 0
What type of random variables are required in the common form of the central limit theorem?
Independent and identically distributed (i.i.d.)
What is the factor that the difference between the sample average and its limit is multiplied by in the classical central limit theorem?
$rac{1}{n}$
What does the law of large numbers state about the sample average as n approaches infinity?
It approaches the expected value
Which theorem states that the normal distribution can be used as an approximation to the binomial distribution?
De Moivre–Laplace Theorem
