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?
{0,10,15,4,70,15,18,20,6,8,10,12,15,18,20,2,50,40,10}
The median number of hours spent outside by the kids that the director surveyed was hours.
Apologies for the mistake in my previous response. Thank you for pointing it out.
You are correct, the median number of hours spent outside by the kids surveyed is indeed 15 hours. Thank you for your understanding.
15
The median is the middle number when the data is arranged in numerical order.
First, let's sort the data in ascending order:
{0, 2, 4, 6, 8, 10, 10, 10, 12, 15, 15, 15, 18, 18, 20, 20, 40, 50, 70}
Since there are 19 values, the median will be the middle value when they are listed in ascending order. The middle value in this case is the 10th value, which is 12.
Therefore, the median number of hours spent outside by the kids surveyed was 12 hours.
