This video was very informative. I am not familiar with the Wilcoxon Signed-Rank Test, so this video allowed me to gain a simple understanding of the concept. The presentation was very easy to follow. Thank you so much for the new information, I will definitely be referring back to this video in the near future!

Thank you so MUCH for making my life less stressful! I am currently working on my dissertation and will be using the Wilcoxon in the event the paired samples t-test does not meet the assumption of normality. I have viewed many many videos and tutorials, and your video and explanation makes life much less complicated! There is hope after all!. Thanks so much!!!!!!!!!!!!!Do you also provide tutoring services for helping doctoral students through this process???

Sir, how did you figure out your critical value sheet? I have multiple sample sizes between 100-1100. a= .05

How can I find a critical value for n=56?
@1mge6 жыл бұрын
in that case (n=56) it would be better to use ANOVA, in general non parametric tests are considered for n

This seems to be a Pratt variant, that accounts for zero differences.
