**Statistics**

As I said before, it would depend on the size of the samples to see if the difference was significant. Based on three pairs, it probably would not be significant. Based on 1000 pairs, the difference probably would be significant. It does not make a different value right or wrong.

You need two different values to find the coordinates, not just one.
