To find the median of the data, you need to organize the scores in ascending order.

0 |8
1 | 2 7 8 9
2 | 3
3 | 1 5
4 | 0
To find the median, we look for the middle value.
Step 1: Count the number of scores in the data set. There are 13 scores.
Step 2: Since there are an off number of scores, the median will be the middle value.
Step 3: Arrange the scores in ascending orders:
0,2,2,2,3,5,7,8,8,9,12,13,15
Step 4: Find the middle value. In this case, it’s the 7th value in the ordered list:
0,1,2,2,3,5,7,8,8,9,12,13,15
So, the median score is 7.
