To find the median, we first need to arrange the list of hours spent on screens in ascending order:

{0, 7, 8, 8, 10, 11, 14, 15, 17, 17.5, 18, 18, 18, 20, 30}

Since there are 15 values in the list, the median will be the average of the two middle values: 11 and 14.

Median = (11 + 14) / 2
Median = 25 / 2
Median = 12.5

Therefore, the median number of hours spent on screens for the kids surveyed is 12.5 hours.
