Question

Find the median of the following distribution:

Answer 1

We have n = 50

So, n/2 = 50/2 = 25

The cumulative Frequency just greater than n/2 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,
