Hi, I used Duncan's multiple range test for post hoc analysis to see the significance of my results with multiple groups.
Thing is, the result is like:
a ab ab abc abcd abcd bcd bcd cd d
Is this possible? Or maybe I should use different methods like Tukey or Bonferroni?
Please give me some advice.
Thank you.
Yes , it is very much possible , this is what Duncans Multiple Range test does....
Therre are numerous of these for instand Firsher Least Signicant Difference is a little bet simpler.
Duncan New Multiple Range Test and Tukey.
You can run they all and select the one or ones you most are comfortable with.
They give very similar differentation in my experinece.
Yes it is possible and true. Duncan's multiple range test generates significance levels for the difference between any pair of means. It means it provides several critical differences between each pair, whereas, for example, the LSD method generates only one.
