The tools are applications that you can use to learn key points, reinforce web text knowledge, and analyze data. Below are the tools and a brief explanation. The full tutorial for the tools will be included in the web text lecture once you get to that point.

The Normal tool makes solving probability questions very simple when you are solving problems which involve the Normal Probability Distribution. The tutorial is in the Normal lecture.

The Binomial tool makes solving probability questions very simple when you are solving problems which involve the Binomial Probability Distribution. The tutorial is in the Binomial lecture.

The Normal Sample tool allow you to take Random samples from a Normal Probability Distribution. The tutorial is in the Normal lecture.

The Sampling Distribution of the Mean tool is a fun way to help you learn a hard concept. The tutorial is in the Sampling Distribution lecture.

Based on your data, StatTool will calculate most standard statistics such as: mean, median, variance, standard deviation, correlation, regression, four kinds of t-tests, chi-square, and analysis of Variance (completely randomized and repeated measures, one-way and two-way). It also graphs data. A tutorial is available.
