mean =sum of observations ÷number of observations.
median (number of observation is even ) =n ÷2 th term + (n ÷2 + 1 )th term divided by 2.
If number of observation is odd = (n + 1 ) 1 ÷2 th term.

mode the variate that has highest frequency known as mode of that observation.

deviation means subtract each number of observation from mean.

Anonymous: plzzz in median arrange data in ascending order or descending order.
