Question

please answer this question
answer is 6.5 but how

Answer 1

first arrange x in ascending order then add all the frequencies you will get 74

now use the formula (n+1)÷2
here n is sum of 'f' you will get 37.5

It means 37.5th term is the median

Now according to the given data 37th term is 6 and 38th term is 7 so the median is
(37th term + 38th term)÷2
(6+7)÷2
13÷2
6.5
