Answer 1

Answer: median- n/2

18/2=9

9+1 =10

9 and 10 unit i.e 13

So 13 is median.

Mode= most repeated number 16

Mean= sum of all numbers divided by no of observations

Explanation: n is no of observations in median . You have to divide n by 2 and add 1 in the answer and the two obtained digits are mean

I cant understand numbers completely so find mean by yourself i have given the formula
