Meaning of Alpha

Published on

  • Students will recognize that the alpha value (significance level of a test) is the relative frequency for sample statistic values that lead to a "reject the null" conclusion, given that the null hypothesis is actually true.
  • Students will recognize that a sample mean can lead to a "reject the null" or "fail to reject the null" depending on the alpha level.

Meaning of Power

Published on

In this lesson, samples are generated from a population for a particular hypothesis test, leading to the conjecture that the null hypothesis is actually false.

Resampling

Published on

This lesson involves approximate sampling distributions obtained from simulations based directly on a single sample. The focus of the lesson is on conducting hypothesis tests in situations for which the conditions of more traditional methods are not met.
