The mean is the same thing as the average. To find the average, add all the numbers up (aka find the sum of the numbers) and divide by how many numbers there is:
$average = \frac{sum \: of \: numbers}{\# \: of \: numbers}$

So the sum of your numbers is: -6 + 2 + 5 + -7 + -11 + -6 = -23. And there are 6 numbers total.
That means average = $\frac{-23}{6} = -3.833333$ ≈ -3.8

Your final answer is -3.8
