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
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
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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pWs-mlCmOi8.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.
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
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
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!
