Tim took a random survey of 20 sixth graders and 20 eighth graders. He asked how many hours a week each played sports. His data
is shown in the two dot plots below. What is the difference between the median number of hours that 6 graders play sports and the median number of hours that 8 graders play sports?
The median number is always in the middle the other numbers have to be equal on both sides 5 is the middle number on the plot 6th graders have 4 dots and 8th graders have 0 dots which means the hourly difference is 4
