Question

Given third quartile is 100 & first quartile is 25 then coefficient of Quartile Deviation

Answer 1

Answer:

The coefficient of quartile deviation of upper quartile 100 and lower quartile 25 is 0.6.

Explanation:

Step 1 : Write down the formula for getting the coefficient of quartile deviation.

The formula is given by :

Let the upper quartile be Q3 and lower quartile be Q1 then the coefficient of quartile Deviation is given by :

Coefficient = (Q3 - Q1) / (Q3 + Q1)

Step 2 : Identify the given values in the question.

Q1 = 25

Q3 = 100

Step 3 : Substitute the values given in the formula.

(100 - 25)/(100 + 25) = 75/125 = 0.6

The coefficient of quartile deviation is therefore 0.6.
