Question 1
In mathematics exam 15 students has obtained following marks out of 25 marks 19, 25, 23,20, 9, 20,15,10, 5,16,25, 20,24,12,20. Find out the mode and median of following observation. Are these same ?

Answer 1

mode ==> 20

median

let us arrange the data in ascending order
5,9,10,12,15,16,19,20,20,20,20,23,24,25,25

since the data is odd , median ==> n+1/2 th term ==> 16/2 ==> 8th term ==> 20


yes median and mode are the same

Answer 2

Answer:

mode =20

median

let us arrange the data in ascending order

5,9,10,12,15,15,19,20,20,20,20,23,24,25,25

since the data is odd ,

median =n+1/2 th term = 16/2 = 8th term = 20

yes median and mode are same.....
