📊Central Limit Theorem Visualization
Sample Mean (X̄) ~ N(μ, σ²/n)
Standard Error = σ/√n
As n → ∞, X̄ approaches normal distribution regardless of population shape

Population Distribution
Distribution of Sample Means
Key Observations:
- The population distribution can have any shape (bimodal, skewed, etc.)
- The distribution of sample means approaches a normal distribution as the number of samples increases
- The mean of sample means equals the population mean (μ)
- The standard deviation of sample means equals σ/√n (standard error)
- Larger sample sizes result in smaller standard error (narrower distribution of means)
- This phenomenon occurs regardless of the original population distribution shape
