Sure it is, depending on the units of measurement.

I'm not doing your homework for you.

What do you mean by unit of measurement? Do you mean m, kg, v? Or something else?

Let me rephrase. It depends on how precisely you measure. For example,let's say a person's grades in a class, a total of 20 grades, average out to an 89% B+. You add a single point to a minor quiz from the semester. It may not necessarily change the 89% to a 90%, assuming you round to the nearest whole number.

Ahh, yes. I understand you completely. Very true. However, I was referring to a situation where the superset average decreases even though a subset average was increased. From that example I am not sure if you understood that.

I present to you the following example:
subset
1, 2, 3
subset average
2
superset
1, 2, 3, 5, 6, 7, 8, 9
superset average
5.125
If we add the value of 4 to the subset
1, 2, 3, 4
the subset average becomes
2.5
while the superset
1, 2, 3, 4, 5, 6, 7, 8, 9
average becomes
5
We have seen a simultaneous increase in the average value of the subset and a decrease in the average value of the superset resulting from the addition of a single value to the subset.

Is my mathematic faulty? Am I using any terms incorrectly? I recently had this debate with somebody and they refused to believe that this was possible.

Yes. I think you are looking at the mean or the mode, not the average.

WAIT I get it!!! If the value added to the subset is LESS than the average of the superset, then it WILL bring it down!!

Yes! The value must be larger than the average of the subset but smaller than the average of the superset. People seem to think that the average of the subset is somehow part of the calculations for the average of the superset, but it's not; only the individual values of the subset are.
