To find the standard deviation, we first need to calculate the mean: 
(2+2+6+10+10)/5 = 6
Then, we find the deviations from the mean for each value: 
-4, -4, 0, 4, 4
Next, we square each deviation: 
16, 16, 0, 16, 16
Then, we find the mean of those squared deviations: 
(16+16+0+16+16)/5 = 16
Finally, we take the square root of that mean: 
sqrt(16) = 4
Therefore, the standard deviation is 4.
