The formula for the median of grouped data is:
A$l + \dfrac{n - cf}{f} \times h$
B$l + \dfrac{\frac{n}{2} + cf}{f} \times h$
C$l - \dfrac{\frac{n}{2} - cf}{f} \times h$
D$l + \dfrac{\frac{n}{2} - cf}{f} \times h$
Answer & Solution
Correct answer: D. $l + \dfrac{\frac{n}{2} - cf}{f} \times h$
Median = l + ((n/2 − cf)/f)·h.
