Write the median

There are $n=35$ data points. Since $n$ is an odd number, the median is the $\frac{n+1}{2}$-th value.

$$\text{Median position} = \frac{35+1}{2} = \frac{36}{2} = 18\text{-th value}$$

The sorted data set is:
12, 17, 18, 21, 23, 25, 25, 26, 27, 28, 29, 30, 33, 34, 35, 36, 37, 37, 37, 37, 37, 37, 37, 44, 45, 46, 46, 52, 53, 53, 56, 57, 61, 62, 62
The 18th value is 37.

$$\text{Median} = \boxed{\text{37}}$$
