Meaning and Definition

If a group  of N observations is  arranged in ascending or descending  order of magnitude then the  middle  value is  called  median of  these  observations  and is  denoted  by M or Me. That  is       M= N+1/2 th  observation.

According  to Prof. L. R. Conner The median is that value  of the  variable which  divides  the group into  two equal  parts  one part  comprising of all values greater and the other all values  less than  the median.

According  to Yule and Kendall " The  median may be  defined  as the middle  most or central values of  the variable  when the  values  are arranged in order of  magnitude or as the value  is such that the  greater and smaller values  occur with equal  frequency.
