If the first quartile 15 and third quartile 5,the quartile deviation is:

Answer 1

Given :-

• First quartile = 15
• Third quartile = 5

To Find :-

• Quartile Deviation = ?

Solution :-

we know that,

• Quartile Deviation = (Third quartile - First quartile) / 2

so,

→ Quartile Deviation = (Q3 - Q1) / 2

→ Quartile Deviation = (5 - 15) / 2

→ Quartile Deviation = (-10)/2

→ Quartile Deviation = (-5) (Ans.)
