To compute the sum of squares, we need to first calculate the mean of the data set. 
Mean = (2+2+3+6+9+13+14)/7 = 7
Then, we subtract the mean from each data point, square the result, and add up all the squared values. 
(2-7)^2 + (2-7)^2 + (3-7)^2 + (6-7)^2 + (9-7)^2 + (13-7)^2 + (14-7)^2
= 25 + 25 + 16 + 1 + 4 + 36 + 49
= 156
Therefore, the answer is A.
