ActivStats Online Statistics Tools

The ActivStats Tools are based on the ActivStats statistics e-book!

The Law of Large Numbers, Random Quantitative Generator and Central Limit Theorem Tools demonstrate fundamental principles important to statistics.

The Normal Table, t Table, Chi-Square Table, and F Table are a convenient way to look up critical values from those distributions.

The Mean Bootstrap, Regression Bootstrap, Quantitative Randomization Test and Binary Randomization Test provide randomization-based ways to perform inference that can be used to supplement classical most frequent inference methods—or even to replace them.

These tools provide built-in datasets, but can also be used with any tab-delimited text data file for which the first row holds variable names.
