Answer:

mode: 7 and 8

median: 5

mean: 5

range: 7

Step-by-step explanation:

the mode is the number that appears most frequently, and 7 and 8 both appear twice.

The median is the middle number when the data is organized from greatest to least. You can work it out by crossing out numbers on either side until you get to the middle. The median was 5.

the mean is the average of all the data in the set. You find it by adding up all the numbers and then dividing by the number of numbers that there are in the data in set. 1+2+3+4+5+7+7+8+8 is 45. And 45/9 is 5.

The range is the biggest number in the data set minus the smallest number in the data set. So 8 - 1 = 7
