Answer:
Increase by 1
Explanation:
Our set numbers: 6, 8, 6, 7, 3, 2, 7, 4, 3, 1
Order: 1, 2, 3, 3, 4, 6, 6, 7, 7, 8
Median: (4 + 6) / 2 = 5
The number 9 was added to the set
Order: 1, 2, 3, 3, 4, 6, 6, 7, 7, 8, 9
Median: 6
How much would the median increase if the number 9 was added to the set?
6 - 5 = 1
So, the median increase by 1 if the number 9 were added to the set.
