I have 7 groups of data. I want to test if there is a significant difference between these groups of data.
However, some of this data is overlapping. ie. some data in Group 1 might be in group 3. Some data in group 6 might also be in group 7 for example. The groups are therefore not perfectly matched.
Secondly, because of this reason, the number of entries in each group are different. For example, group 1 has 54 entries, whereas group 4 has 94 entries.
Is there a particular test I can use to test if there is a significant difference between the groups?
I hope I have made this clear. Many thanks for your help.
