Answer:
8.11
Step-by-step explanation:
4+4+7+13+12+9 = 49
divide that by 6
Answer: Median = 8
========================================================
Explanation:
Sort the data set to go from {4,4,7,13,12,9} to {4,4,7,9,12,13}
Next, cross off the first and last items to get this smaller set: {4,7,9,12}
Repeat the last step to get this even smaller set: {7,9}
We can see that 7 & 9 are tied for the middle most positions. Add them up and divide by 2 to find the midpoint
(7+9)/2 = 16/2 = 8
The median is 8
