The Wilcoxon test, or Wilcoxon signed-rank test, checks whether two dependent samples differ significantly from each other. The Wilcoxon test is a non-parametric test and is therefore subject to significantly lower requirements than its parametric counterpart, the t-test for dependent samples. Thus, as soon as the boundary conditions for the t-test for dependent samples are no longer fulfilled, the Wilcoxon test is used.
Type of Material:
Animation
Recommended Uses:
Lecture support
Homework help
Individual learning
Exam review
This collection would be useful for self-guided study/review, self-paced and individual student practice. As well, for anyone who is doing statistical research.
Technical Requirements:
Video, Website
Identify Major Learning Goals:
Students can define the Wilcoxon signed-rank test, can explain when to use a non-parametric test instead of a t-test, can perform hypothesis testing with paired data, and can interpret results (test statistic and p-value).
To know that when the boundary conditions for the t-test for dependent samples are no longer fulfilled, the Wilcoxon test is used.
