Question

1 . The scores in mathematics test ( out of 25 ) of 15 students is as follows :

19 , 25 , 23 , 20 , 9 , 20 , 15 , 10 , 5 , 16 , 25 , 20 , 24 , 12 , 20 .

Find the mode and median of this data . Are they same ? ​

Answer 1

Answer:

First we will find the mode of the data :- 19, 25, 23, 20, 9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20

20 have occurred 4 times ∴

The most frequently occurring value =  20                                                                     Therefore the mode of the given set of data is 20

Now Median;

Numbers arranged in ascending order  = 5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25

So the middle value here is 20.

Median and Mode both are same.
