Finding the median for grouped data when class intervals are given. Step 1: find the cumulative frequency for all class intervals. Step 2: the median class is the class whose cumulative frequency is greater than or nearest to n2, where n is the number of observations. Step 3: M edian = l + [ (N/2 – cf)/f] × h.Statistical methods are employed extensively in the production of such reports.
