Answer 2

Answer:

the quartile deviation is given by 20

Step-by-step explanation:

According to the question, it is given that

upper quartile or Q3 = 50

and lower quartile or Q1 = 10

quartile deviation is given by the formula Q.D =  $\frac{Q3 - Q1}{2}$

implies quartile deviation = (50-10)/2

that is Q.D = 40/2

that is Q.D = 20

therefore the quartile deviation is 20
