Question

Find mean and median of given data 12,63,26,47,85,30,51,62,20​​

Answer 1

Answer:

here is your answer,

mean=12+63+26+47+85+30+51+62+20=396/9=44

so,mean of given data =44

median=n+1/2 for odd term.,arranging in ascending order i.e 12,20,26,30,47,51,62,63,85

now,here n=9

so, 9+1/2=10/2=5th term

so,the 5th term is 47
