in two factorial, ANOVA how to denote letters if the test between effects is significant.. is it possible that means denoted with two letters e.g. mean is 3.45 ^ a, ab
I just used a Games-Howell test. How can I have compact letter display automatically with a code. Does cldList() work? Struggling with it as the output for GHT features "group1" and "group2" as columns, not one fusioned "comparisons" column. Probably trivial, but I don't see any solution at this point. Help very much appreciated here!
Hello Simon, you can have it automatically using the multCompView package. You can check it on my video ruclips.net/video/pWs-mlCmOi8/видео.html or in the page statdoe.com/two-way-anova-in-r/ However, the examples are for Tukey's test, although it should work for other tests.
At 3:56, assuming 0.71 and 1.4 were not significantly different, how do I draw the line? Do I draw it from 0.71 all the way to 1.4 or do I skip 1.02? The video was amazingly helpful, by the way. Thank you!
Thanks very much, Rosane. You are the best. I have a query though please and need your help. There are four treatments with descending order of averages being 56,19, T and 17. For the pair, 17-19 p > 0.02. For all other pairs, p
Thank you, your videos are very helpful. Can you advise on how to add superscript to show significance with many pairs - I have 16 means, so 121 pairs. Comparing them using the manual method is too confusing.
Hello Niamh, I learnt a way of R to generate the letters for indicating the significant differences using the multicompView package. Taking the example of the tutorial, you must run the following code: # comparing means by Tukey's test install.packages("multcompView") library(multcompView) tukey.rr
I have 4 values 54.6, 50, 28, 23.8 according to tukey's test there was no significance among each other how can i assign letters in this case madam.. please help me
Itz same method sir. I jst computed it and compare the superscripts with those I got in Rstudio for same data I computed in spss. Once you understand this method then you're good to go.
@@aaronayubasamaila8821 So I have 121 pairs to compare and it is too complicated/laborious using this method, do you have a method to compute the superscript? Thanks!
Наука
Smart way! It's much simpler than the method I learnt to compare down and up etc. Thank you!
thank you, Roseane. It helps me a lot
Thank you so much.. Search all over for this
Glad I could help
thank you for this video. It's very useful.
Thanks Roseane!
Thank you so much!! I have 15 means to compare and this made things so much easier...!
I am happy it helped you!
Thank you. Is it possible to count the superscript from spss independent t test?
I found it very helpful. thank you Professor
You are welcome!
Thanks for the information
very helpful!!!!
Dear Dr. Rech, Thank you for this video. Could you possibly share and example how follow this for multiple plots at once using "facet wrap",
dr. Rech your teaching is a lovely one!! please do on fertilizer rate of phosphorus and potassium by RCBD design
Muito origado pelo vídeo! Ajudou demais a entender essa confusão de letra.
Thank you mam..

I am so confused. How do you tell the significance? Is it by seeing if they are in close range or maybe far apart or what
very useful madam
Thanks, vert helpfull
Glad it helped

Question, if all the results shows no significant for all treatment, Do I need to draw only one line which is 'a' as you mentioned just now?
Same question. Just that ours is all significant.
Thank you so much
You're most welcome
This was very useful! I was wondering whether this manually grouping method can be used for analyze the results of a non-parametric post hoc test?
It can, the idea continue to be the same.

Sorry, it is not correct. Remember to put them in decreasing order.
@@RosaneRech Thanks for answering. i realized there was an error earlier on. It is resolved now.
@@RosaneRech can it be arranged in increasing order instead?

@@RosaneRech Thank you so much! I tired a number of things without success but this works perfectly and is so simple. As are your other examples.
@@niamhpatterson2468 I try to simplify as much as possible the codes. Glad it worked for you.

I used graphpad prism to get statistical differences...is it right like this- 54.6a, 50 a, 28a,
Wait for the answer !
How can this process be automated using SPSS

I am not familiar on working with SPSS, but considering it is a great and complete software, I would guess it is possible to do on it.
How can i use superscript from spss independent t test? Please help. I literally stuck with it😭😭
Sorry, your video is not useful, it's super useful. Many thanks
Thanks Jacky! :-D
