How to find median for even number of observations with frequency?

This is how you'll do

Median formula= L+[(n/2-c.f)/f]×h
it is the formula for grouped data
here data arranged in proper way means with class intervals and also with cumalative feequency.Here after arranging we have to find median class by a measure of n/2(the c.f value of class exceeds this value for the first is the median class)
where L= liwer boundary of median class
n =no.of.observations
c.f= cumalative frequency preceding the median class
f = frequency of median class
h= class size

hope it helps

Hi... Write the list of numbers in order from smaller to largest. Cross off the same amount of numbers at each end of this ordered list until two numbers remain in the middle... Ok then Add these two numbers together and divide the result by 2 to get the median.Hope it helps you :)

Hope it helps you my friend...

galvanometer g shows zero deflection. if the batteries a and b have negligible internal resistance, the value of the resistor r will be.
