To find the mean of the numbers shown in the image, follow these steps:

Numbers given:

16, 9, 21, 29, 31, 35, 8, 37, 24, 25, 14, 23, 1

Steps:

1. Add all the numbers together:

   $16 + 9 + 21 + 29 + 31 + 35 + 8 + 37 + 24 + 25 + 14 + 23 + 1 = 273$

2. Count the number of values: There are 13 values.

3. Calculate the mean:

   $\text{Mean} = \frac{273}{13} = 21$

So, the mean of the numbers is 21.
