## Statistics Tutorials

Fundamentals of Statistics 1: Basic ConceptsIf 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.

Fundamentals of Statistics 2: The Normal DistributionThis 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.

Fundamentals of Statistics 3: SamplingSampling distributions, the standard error and applying the normal distribution to make predictions will become the foundation for almost everything you do in statistics.

## Calculators

1 Sample t-testCompares the means of one data-set against a test mean using the t-distribution.

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

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