Question

The score in mathematics test of 15 students is as follows: 19,25,23,20,7,20,15,10,5,16,25,20,24,12,20. Find Mean, mode and median of the data.​

Answer 1

Answer:

Let's know the meaning of the terms "Mode" and "Median"

Mode = The no. which is occurring most frequently in a set of numbers is called Mode

Median = Median refers to the value which lie in the middle of the set of numbers (When arranged in ascending or descending order).

Now Coming to the question :-

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.
