What do double superscripts mean in an ANOVA table of 'ad hoc' results What is this alphabet (a,b,c) and what does its combination mean in the table?
I have read a lot of literature similar to my work and it shows that most of the researchers have used different superscript letters a, b, c, and d along with the data. It is written "the values with different superscript letters in a column are significantly different (p<0.05)"


Each subscript letter that is different for each parameter shows a significant difference, for example here: in the first row: there is no significant difference between A and B, nor is there a difference between D and E, but:
A and B are different from other groups, and F is different from all groups, and so on.
