Sampling Distribution Simulator

Demonstrates the Central Limit Theorem and the concept of a sampling distribution interactively.


What it does

  • Adjust the population shape (normal, skewed, uniform, bimodal)
  • Set the sample size (n)
  • Choose the number of samples to draw
  • Watch how the distribution of sample means takes shape

Key concepts illustrated

  • The sampling distribution of the mean becomes approximately normal as sample size grows, regardless of the population's shape
  • Larger samples produce a narrower sampling distribution (smaller standard error)
  • The mean of the sampling distribution equals the population mean

This is a teaching tool — it generates illustrative data to build intuition, not to analyse your data.
