In order to find the median number of hours spent outside, we first need to order the data from least to greatest.
{0, 2, 4, 6, 8, 10, 10, 10, 12, 15, 15, 15, 18, 18, 20, 20, 40, 50, 70}
Since the list has an odd number of values (19), the median will be the middle value.
Median = 15 hours
Therefore, the median number of hours spent outside for the kids surveyed was 15 hours.
The director of a local Parks and Recreation department is interested in the number of hours kids spend outside each week. She surveys a group of 19 kids in her town and asks them how many hours they spent outside last week. Her results follow. What was the median number of hours spent outside for the kids she surveyed?
