Statistics Tutorials

If you know nothing about statistics, this is the place to start. The tutorial covers basic concepts such as the mean, standard deviation, populations and sample statistics.

This tutorial continues where Fundamentals I left off. It covers the normal distribution in detail including how to find the probabilities of events using the normal curve.

Sampling distributions, the standard error and applying the normal distribution to make predictions will become the foundation for almost everything you do in statistics.

Calculators

Compares the means of one data-set against a test mean using the t-distribution.

Calculates the percent of area under the student t distribution given a t-score and degrees of freedom.

Calculates the critical value from the student t distribution given a proportion of area and degrees of freedom.
