Median means middle. You must find the middle of this set of data. To do this you must first order the data from least to greatest:
3, 3, 4, 5, 5, 5, 6, 6, 7, 8
Now on each "level" remove the largest and the smallest number until you get to the middle number(s)
3, 3, 4, 5, 5, 5, 6, 6, 7, 8
3 , 4, 5, 5, 5, 6, 6, 7
4, 5, 5, 5, 6, 6
5, 5, 5, 6
5, 5
Since there isn't exactly one number in the middle you must take the mean (average) of the two numbers left. To do this you must add the remaining numbers, 5 and 5, together then divide by 2
5 + 5 = 10
10 ÷ 2 = 5
The median of this data set is 5
Hope this helped!
