WebSummary. For grouped data, we cannot find the exact Mean, Median and Mode, we can only give estimates. To estimate the Mean use the midpoints of the class intervals: Estimated Mean = Sum of (Midpoint × Frequency) Sum of Frequency. To estimate the Median use: Estimated Median = L + (n/2) − B G × w. where: WebBut in this concept of class 10th we will study how to find median of grouped data. The formula to find median of grouped data is Median= l + { ( N 2) - c f f } × h l= lower limit of the median class N= ∑fi= sum of the frequencies cf= cumulative frequency f= frequency of the median class h= Class size Example- Find the median of the following data:
