B. It is the same as the original median.
Step-by-step explanation:
- The original set of data contain 7 items.
- Median term for odd number of set = (no. of items+1) / 2
Median term = (7+1) / 2 = 8/2 = 4.
The median of the original set is 4th term of the 7 items.
- The new set has 11 items in which 2 items are added in the beginning and 2 items are added in the end of the original set.
- Now, the 4th term of the original set becomes the 6th term of the new set.
Median term of new set = (11+1)/2 = 12/2 = 6.
The median of the new set is 6th term of the 11 items.
- The 4th term of original set and 6th term of new set are same.
- So, the median remains the same.
