Question

21, 22, 23, 23, 23, 34, 26, 23, 26 find the mean and the median

Answer 1

mean=sum of all/no. of all
mean=21+22+23+23+23+34+26+23+26/9
mean=221/9=24.55
let us arrange it in ascending order
21,22,23,23,23,23,26,26,34
median(odd)=(n+1/2)th obs.
=9+1/2
=5th obs
=23

Answer 2

mean
add the total number and divided by number
21+22+23+23+23+34+26+23+26\9
answer 221/9
=24.5555556


median
21+22+23+22+23+34+23+26+23 and find is middle terms and add it and divided by number of terms
the middle terms are 23+23+34/3
ans 80/3
26.6666667
