Median of Grouped Data — Identifying the Median Class and the Interpolation Formula

Identify the median class using the N/2 criterion; extract the components $L_1$, $cf_m$, $f_m$, $C$, and $N$; apply the interpolation formula $\text{Median} = L_1 + \frac{N/2 - cf_m}{f_m} \times C$; and verify the result against the ogive.
