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

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

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 kzfaq.info/get/bejne/pr2jYNCdqNOzmWw.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.

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.

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!

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 3 жыл бұрын

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 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.
