Find the median of the following data 31, 38, 27, 28, 36, 25, 35, 40

Explanation

Write the observations on ascending order=`25,27,28,31,35,36,38,40`
Number of observations(N)=`8`
Since N is even
Median=`("Value of" (N/2)th " observations" + "Value of" ((N/2)+1)th " observations")/2`
=`("Value of" (8/2)th " observations" + "Value of" ((8/2)+1)th " observations")/2`
=`("Value of 4th observations + value of 5th observations")/2`
`=(31+35)/2=66/2=33`
