One-Way ANOVA 3 - Using Superscript Letters in Tukey's Test

[@katelyn6435]

Smart way! It's much simpler than the method I learnt to compare down and up etc. Thank you!

[@atanea2867]

Thank you so much.. Search all over for this

[@RosaneRech]

Glad I could help

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!

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

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",

[@danialharis9374]

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?

[@sooshichan]

Same question. Just that ours is all significant.

Thank you so much!! I have 15 means to compare and this made things so much easier...!

I am happy it helped you!

[@devindeelakdika3259]

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?

[@RosaneRech]

It can, the idea continue to be the same.

thank you, Roseane. It helps me a lot

[@chintumofu3463]

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

[@Gushpuppies]

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

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.

[@hazeltee3508]

@@RosaneRech can it be arranged in increasing order instead?

Thank you. Is it possible to count the superscript from spss independent t test?

[@simonyoung6880]

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!

[@RosaneRech]

Hello Simon, you can have it automatically using the multCompView package. You can check it on my video kzbin.info/www/bejne/pojWXqCieNKCn5o 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.

I found it very helpful. thank you Professor

You are welcome!

[@niamhpatterson2468]

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.

[@RosaneRech]

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

@@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.

How can this process be automated using SPSS

[@aaronayubasamaila8821]

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.

[@niamhpatterson2468]

​@@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!

[@RosaneRech]

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.
