The director of a local summer camp is interested in the number of hours kids spend on screens each week. He surveys a group of 15 kids at his camp and asks them how many hours they spent on screens last week. His results follow. What is the range of his data?
{18,8,8,7,10,14,15,11,17,17.5,18,0,18,30,20} (1 point)
The range of the number of hours spent on screens by the kids that the director surveyed is
hours.
The range is calculated by finding the difference between the highest and lowest values in the data set.
Highest value: 30
Lowest value: 0
Range = 30 - 0 = 30
Therefore, the range of the number of hours spent on screens by the kids that the director surveyed is 30 hours.
