Which is the correct formula for median of grouped data?
Consider:
L = lower limit of median class
CF₀ = cumulative frequency of preceding class
F = frequency of median class
H = class width
N = the total of frequency
\(\frac{\frac{N}{2}-CF_0}{F}\times H\)
\(L+\frac{\frac{N}{2}-CF_0}{F}\times H\)
\(L+\frac{\frac{N}{2}-CF_0}{F}\)
\(L+\frac{N}{2}-CF_0-F\times H\)
