WebBy extension, you can also use the central limit theorem when examining the sum or average of independent random variables (even if those variables are not normal). Example: Using The Central Limit Theorem For A Discrete Random Variable (Average Of N 6-Sided Dice Rolls) A 6-sided dice roll is a discrete random variable. Web7.2 The Central Limit Theorem for Sums. Highlights. Suppose X is a random variable with a distribution that may be known or unknown (it can be any distribution) and suppose: μX = the mean of Χ. σΧ = the standard deviation of X. If you draw random samples of size n, then as n increases, the random variable Σ X consisting of sums tends to be ...
