Dear my friends,
I am a computer science student, and I have a set of data. My data is divided in two groups (size of each group: n1=3928 and n2=26). Each element of these groups has one specific score and scores of each group have been normalized with a min-max normalization (min=0, max=1).
I need a statistical test which proves that one specific value, for example 0.4, can separate these two groups.
I used t-test; however, I am not sure I have applied it correctly (and I am not sure that the t-test is a suitable one or not).
Any help is really appreciated
