Statistical Simulations

Explore the surprising probability of shared birthdays in a group

Visualize how sample means converge to the true population mean

Visualize bootstrap resampling to estimate sampling distributions and construct confidence intervals without assumptions

See how sample means follow a normal distribution regardless of the population distribution

Understand how confidence intervals capture the true population parameter

See how sample statistics vary across repeated samples with a three-panel population, sample, and sampling distribution view

Visualize Type I/II errors, statistical power, and p-value distributions by running hundreds of hypothesis tests

Use random sampling to solve complex probability problems

Visualize the meaning and interpretation of p-values
