(i) 5, 7, 9, 11, 15, 17, 2, 23 and 19
(ii) 9, 3, 20, 13, 0, 7 and 10
(iiiy 18, 19, 20, 23, 22, 20, 17, 19, 25 and 21
(iv) 3.6, 9.4, 3.8, 5-6, 6-5, 8.9, 2.7, 10.8, 15.6, 1.9 and 7.6.​

Answer 1

Step-by-step explanation:

median is always the centre no. of the no. of digits are given. First we have to arrange the digits in ascending order in every case as it will make it more easy to find out the median. Then we have to take out the centre. It is very easy to tell the median of (i) , (ii) and (iv) as the total no. of digits are odd but in case of (iii) the total no. of digits are even so we have to take two centre digits , add them and divide it by two that will be our median.
