Question

What is the third quartile of this data set 20,21,24,25,28,29,35,37,42,43,44

Answer 1

42

Explanation:

We are given that a data set

20,21,24,25,28,29,35,37,42,43,44

We have to find the value of third quartile of the given data set.

To find the third quartile we will use the given below formula

`Q_3=(3)/(4)* (n+1)^(th) term`

Where n=Total number of term

We have n=11

By using the formula

`Q_3=(3)/(4)* (11+1)^(th)` term

`Q_3=9^(th)` term

`9^(th)` term=42

Hence, third quartile=42

Answer 2

42
