Question

find the mode and medain of the data 10,14,10,15,13,12,10,10,11 ​

Answer 1

Step-by-step explanation:

To find the median, we'll have to arrange it in an ascending order

i.e. 10,10,10,10,11,12,13,14,15

Here, n= 9 terms

In order to find median of odd n terms, the formula given below can be used,

Median= (n+1/2)th term

i.e. Median=(9+1/2)th term

On simplifying, we get

Median= 5th term

In the ascending order sequence the 5th term is 11.

In the ascending order sequence the 5th term is 11. Therefore, Median= 11

To find Mode, we'll look up for the number which appears more often

As the number 10 is repeated maximum times, therefore, Mode= 10
