Answer

So, the mean is $\boxed{12.89}$

Steps

Step 1 ：First, add up all the numbers: $10 + 10 + 11 + 12 + 14 + 14 + 14 + 15 + 26 = 116$

Step 2 ：Next, count the total number of numbers, which is 9

Step 3 ：Finally, divide the sum by the count to find the mean: $\frac{116}{9} = 12.89$

Step 4 ：So, the mean is $\boxed{12.89}$
