2. your name I dont know

Answer 2

Given,

First Quartile Q₁ = 20.58

Third Quartile Q₃ = 60.38

To find,

The Quartile deviation (QD)

Solution,

The Quartile deviation of the data whose first and third quartiles are 20.58 and 60.38, respectively, is 19.9.

We can simply find the quartile deviation by using the formula

QD = Q₃ - Q₁/2

QD = 60.38 - 20.58 /2

QD = 39.8/2

QD = 19.9

Hence, the Quartile deviation of the data whose first and third quartiles are 20.58 and 60.38, respectively, is  19.9.
