since its a discrete series, median = size of (n+1/2)th item
x          f      cf
160     12     12        
150      8      20         
152      4      24        
161      4      28          
156      3      31       
154      3      34      
155      7      41     
 total    41

  m=size of (41+1/2)th item
     =size of (42/2)th item
     =size of (21)th item
     =    152                 
                       
        therefore , 152 is the median
