## Tools

- [Central Limit Theorem Demonstrator](https://elysiatools.com/en/tools/central-limit-theorem-demonstrator): See the Central Limit Theorem in action: draw samples from a non-normal source distribution (uniform, exponential, Poisson, or Bernoulli), plot the histogram of sample means, and overlay the predicted Normal curve N(μ, σ²/n). Compare empirical vs theoretical mean and standard error, and watch convergence tighten as the sample size grows.
- [Normal Distribution Calculator](https://elysiatools.com/en/tools/normal-distribution-calculator): Calculate z-scores, cumulative probability, tail probability, and interval probability for a normal distribution
- [Skewness Analyzer](https://elysiatools.com/en/tools/skewness-analyzer): Analyze data skewness to measure the asymmetry of probability distribution and identify data patterns
- [Z-Score Calculator](https://elysiatools.com/en/tools/z-score-calculator): Calculate a z-score from a raw value using a dataset or manually entered mean and standard deviation
- [Z-Score to Percentile Calculator](https://elysiatools.com/en/tools/z-score-to-percentile-calculator): Convert a z-score into normal-distribution percentile, tail probability, or central area
