Calculate the value of median from the following data:Income12,001,8005,0002,5003,0001,6003,500No. of Persons12162103157

Answer»
IncomeNumber of People(f)Cumulative Frequency(c.f.)
12001212
16001527
18001643
25001053
3000356
3500763
5000265
                    N = 65

Median = size of \((\frac{N+1}{2})^{th}\) item

Median = \(\frac{65+11}2=33^{rd}\) 

While locating the item in the Cumulative Frequency column, the item that exceeded 33rd is 43 that is corresponding to 1800. Thus, the median is 1800.
