You don't divide by the number of years but take the nth root of the number of years that will give you the correct average annual return calculation.

Total compounded return = (1+ Year 1 Return) * (1 + Year 2 Return) * ... * (1+ Year N Return)

Average annual return = (Total compounded return)^(1/N) - 1

For your data I get a 15.02% average annual return over the 12 years.
