Question

Write the formula to calculate median for grouped data

Answer 1

arrange all numbers to ascending to desending and formula is n+1÷2

Answer 2

For the given data, we need to have class interval, frequency distribution and cumulative frequency distribution. Then, median is calculated as  

Median = [l+[n/2 - cf] /f] h

Where

l = lower limit of median class,  

n = number of observations,  

cf = cumulative frequency of class preceding the median class,  

f = frequency of median class,  

h = class size (assuming class size to be equal)
