Compute the median for each of the following data

(i)


We have, N = 100




= 50


The cumulative frequency just greater than is 65 then median Class 70-90, such that:


l = 70, f = 22, F = 43, h = 20






= 70 + 6.36


= 76.36




(ii)




We have, N = 150




= 75


The cumulative frequency is just more than is 90 then, the Median Class is 110-120 such that:


l = 110, f = 45, F = 45, h = 10







= 110 + 6.67


= 116.67
