We had to do a RC Circuit experiment in the lab one step in the procedure goes as follows:

Question

Record the time needed to discharge a capacitor from 10.0 V to 9,8,7,6,5,4,3, and 2 V. Repeat once.

The QUESTION BEING ASKED IS: Can you find the time to discharge the capacitor to V0 = 0.0 V experimentally? Is it practical? Explain.

(I am wondering, if you take the average would it give you the time to dischage to 0, if not what would? PLEASE HELP)

Voltage will never get to zero as an expontential decay. Normally, we use five time constants as the time to get to zero. You can get the time constant from the decay graph.
