t-distribution

Many textbooks cover the t-test and t-distribution. We go further with this dynamic illustration. Engage the t-distribution by adjusting n, the sample size, as well as alpha.

Concepts taught include:

• p-values and hypothesis tests (t-test)
• t-values
• z-scores
• sample-size effect on t-distribution and t-tests
• alpha, Type I errors
