Correct option is B
Given:
15, 70, 34, 37, 25, 36, 74, 36, 54, 78, 33
Concept Used:
For Ungrouped data; for odd number of terms
the middle term is the median.
Solution:
Rearranging data in ascending order
15, 25, 33, 34, 36, 36, 37, 54, 70, 74, 78
There are 11 numbers (which is odd), so the median is the middle value, which is the 6th term
The 6th value in the sorted list is 36
