Art of Stat: Resampling

Modern statistical calculator for teachers and students of statistics.

The Art of Stat: Resampling app lets you find bootstrap confidence intervals and permutation P-values. The app illustrates the procedures interactively so you can understand how they work. Several example datasets are preloaded for you to explore, but you can also enter your own data or import a CSV file.

The following resampling methods are implemented:

- Bootstrap Confidence Interval for a population mean, median, or standard deviation.
- Bootstrap Confidence Interval for a population proportion or population odds.
- Bootstrap Confidence Interval for a population correlation (Pearson and Spearman) or the population slope of a regression model.
- Bootstrap Confidence Interval for the difference of two population means or medians.
- Permutation Test for a population mean or median.
- Permutation Test for the difference of two population means or medians.

Coming Soon:
- Permutation Test for the independence of two categorical variables (Permutation Chi-Squared Test)

Easily find the bootstrap confidence interval based on the percentile method. For inference about the population mean, compare results to traditional methods based on the Student-t distribution.

The app has a Data Editor spreadsheet for you to enter (and save) your own data.
