In grouped data, the median class is found where cumulative frequency just exceeds \(n/2\). Then apply the formula \(L + \frac{(n/2 - cf)}{f} \times h\), minding the class boundaries. It is a careful calculation I perform each month for our district's ration card reports. Yet, in our village, the true median lies in the stories behind the numbers—like the three new widows last year who shifted the column—so I check my figures twice and bless the ledger.
