Probability & Distributions

Probability Distributions & Simulation

Calculate probabilities and critical values, explore continuous and discrete distributions, generate random data, and investigate sampling behavior through interactive statistical tools.

For confidence intervals and hypothesis testing, explore our statistical inference tools .

Sampling

Investigate sampling distributions, the Central Limit Theorem and the Law of Large Numbers through repeated random sampling.

Observe convergence of the sample mean

Follow running sample means as more observations are added and compare them with the theoretical population mean.
