The median is the number in the middle of the data once it is organized from least to greatest, so that is what we must do first.
![2,5,7,8,8,11,12,14,20,23,23,25,27,28,29,31,36,36,42](https://img.qammunity.org/2020/formulas/mathematics/middle-school/leeq7dtz1xbi60yxanq8aqmgj4lndr0tm1.png)

This means that the median is 23
