Answer 1

to find mean median and mode first arrange the following numbers in ascending order.and then apply formula given in you're maths text book you will get answer ☺☺☺ ...

Answer 2

Here is the answer........

mean = (15+13+9+9+7+1+11+10+13+1+13)/11

=102/11

=9.27

mode= most occuring no.= no. with highest frequency=13

median in ascending order.......

=1,7,9,9,10,11,13,13,13,15.

median....when n is odd:-

=(n+1)/2^th term

=6 th term

=11
