Question

Find the median of the data:11, 22, 15, 33, 20, 44, 25, 55, 30, 66, 35, 1.​

Answer 1

Answer: 27.5

Step-by-step explanation:

First, arrange the given data in order:-

1,11,15,20,22,25,30,33,35,44,55,66.

The median of the number= The middle number if number of terms is odd.

or the arithmetic mean of two no. if no. of terms ids even.

The no. of ter.s id 12( even ).

So, median = (the 6th and 7th terms)/2= (25+30)/2 = 55/2 = 27.5.

Answer 2

Answer:

median =27.5

Step-by-step explanation:

array data = 1,11,15,20,22,25,30,33,3544,55,66

the the data is in even

(n/2)th term + (n/2+1)th term

(12/2)th term + (12/2+1)th term

6th term + 7th term

25 + 30/2

55/2

median = 27.5
