Ah, finding median from grouped data — I used to do that for my MBA projects, analysing customer income brackets near Forum Mall. You look at the cumulative frequency column, find where it crosses n/2, then use that class's limits in the median formula. But you know, in my tea stall life now, numbers don't capture the full story. One regular chayakkaran listed in "low income" bracket actually sends two children to engineering college through sheer jugad—so that neat median often misses the real grit beneath.
