Calculate Median From The Following Data Class 10. To calculate the median from a set of values enter the observed values in the box above. By arranging the data in ascending order we get as follows and we calculate median with the help of following data.
Mean 105 and median 96. Median 2 Where lower limits of median class N sum of frequencies frequency of median class C Cumulative frequency of class before median class Here 20 N 50 C 14 10 14 Median 2 20 502 1414 10 20 25 1414 10 20 1114 10 20 78. Median of Grouped Data.

The cumulative frequency just greater than 615 is 65 and the corresponding class is 155 205.
