Find the median of the following data...

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

Text Solution

Verified by Experts

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`
