Explain the Central Limit Theorem (CLT).
Explain the Central Limit Theorem (CLT).
Approach: Describe the convergence of the sum of random variables to a normal distribution.
A theorem stating that the distribution of the sum (or average) of a large number of independent, identically distributed variables will be approximately normal, regardless of the underlying distribution, provided they have finite variance.
Follow-up: How large does the sample size N usually need to be?
Key concepts: independence, sample mean, gaussian.
