Answer:
9
Step-by-step explanation:
Let's find the median:
12,9,16,1,6,5,84 ,12 , 9 , 16 , 1 , 6 , 5 , 84
We have to rearrange this to be least to greatest.
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
In order to find the median, we have to find the middle of that set.
You do that by eliminating each number one by one on each side until there are 1 or 2 numbers.
Bold = eliminated
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
1, 1, 5, 5, 6, 6, 9, 9, 12, 12, 16, 16, 84, 84
The last 2 numbers that aren't eliminated are 9 and 9.
The middle of 9 and 9 is 9 because they are the same number.
The median of the data set is 9.
