Central Limit Theorem
Use this page to demonstrate that sample means from skew distributions become closer to normal as the sample size increases. (The population is an exponential distribution, so the sample means have gamma distributions with different shape parameters.)
Initially click Accumulate then take several samples. Change the sample size and repeat, showing that with larger sample size,
Select Theoretical distributions from the pop-up menu at the top. Use the slider to show the theoretical gamma distributions for the means of samples of different sizes.
