Wilcoxon Signed-Rank Test in Excel

[@marisamaguire8136]

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 Dr Grande. This video was easy to follow and very informative. I find it very interesting especially since I am writing a project that includes pretesting and posttesting

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???

[@lawrence2467]

Very clear and straight forward, thanks for making this video!!!

[@MaggiLuis]

Thank you Dr Todd. It was very useful

[@mohammedfawzyhabib5961]

thanks alot sir,, the video was of great help ,, I have a question , how can we determine the p value of this test ?

[@sarahjones208]

I liked this video because it helped me understand the importance of a Wilcoxon test.

[@hendmahmoud11]

Great video. I just would like to know if we should follow the same steps if are the values are positive?

[@munnabahadur8526]

Thanks for it. Where can we find out the list of critical value for 120 samples size? Thank again.

[@joshchen9972]

Does this work if there are records where the there is no change, (i.e. sign is 0)?

[@surakham]

Why are most of the pretest scores higher than those of the post-test?

[@Erzeshan]

Where to get the critical value table Doctor?

[@richardcurtis6764]

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

[@dr.mahaboobbasha1074]

Why you considered lower value as a calculated one

[@sachinmoghe7283]

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

[@ibraheemOmar]

Great

How can I find a critical value for n=56?

[@1mge]

in that case (n=56) it would be better to use ANOVA, in general non parametric tests are considered for n
