The distribution below gives the weights of 30 students of a class. Find the median weight of the students.
Solution:
Cumulative frequency greater than
is 19
So, median class = 55-60
Median
where, l = lower limit of median class = 55
n = number of observations = 30
cf = cumulative frequency of class preceding the median class = 13
f = frequency of median class = 6
h = class size (assuming class size to be equal) = 5
Median
kg
