B.
2 -
C.
3 -
D.
4
Correct Answer: Option C
Explanation
Total frequency = 1 + 2 + 7 + 5 + 4 + 3 = 22
Median is the middle number
= (frac{Nth}{2})
term = (frac{22th}{2}) = 11th term
Going in ascending order, 11th term is 3, going in descending order 11th term is 3
Median = 3 + (frac{3}{2}) = (frac{6}{2}) = 3
Answer is C
