Find the median of the following distribution:


We have n = 50


So,


The cumulative Frequency just greater than is 36 then the median class is 10.75 – 11.25 such that


the lower limit (l) = 10.75


cumulative frequency of the class preceding 10.75 – 11.25 (cf) = 19


frequency of the median class 10.75 – 11.25 = 17,


class size (h) = 0.5


Using the formula,, we have



= 10.75 + 0.176


= 10.93
