first you set the correct numerical order
{1,2,2,3,3,4,4,6,7,8,8,9} then you have to find the mean which you add all the numbers together which is 57 and then you have to find the median which is the middle number if its to you add them then divide by 2 which you have 4 and last is the mode which is when the number repeats itself which is 2,3,4, and 8 so it should look like this
mean-57
median-4
mode- 2 3 4 and 8
and the numerical order
