How to find average angular velocity?

Homework Statement

I had a physics lab and we found the 3 trials of revolution in 2 min then the result came as 1st=344rev
2nd=332rev
3rd=330rev
(These numbers is from the calculation of Final (2min) - Initial start)
Then it asked to find the average angular velocity for three of results.

Homework Equations

1 rev= 2pi rad/60s

The Attempt at a Solution

First I added all the revolutions 344+332+330 then converted to get average angular v
Did I got it right?
EDITED

I am not sure what is spinning, but why is your 3rd trial value so high?? The average number of revolutions is the sum of the revolutions divided by three; once you get this average, then the average angular velocity is per your equation, but with the corrected value for the average number of revolutions inserted therein.

my bad. the 3rd is 330rev.
Umm I'm not quite follow.
