This copy detector is an auto-pilot version of the original cheat checker that could point to the source person. Here (Sheet 8) a pairing index ranks answer sheets by the degree of pairing (Sheet 9).
An interesting feature of this right marked scoring (RMS) nursing test is that Unique pairings (red) occurred only toward the end of the test.
There is no distinct break in the beginning of the pairing index and at the end of the pairing count plots to indicate cheating.
