In a town 25% of the person earned more than Rs. 55,000 where as 75% earned more than 20,000 calculate the absolute and relative value of disperson
Answers
Absolute value of dispersion = Rs 17,500
Relative value of dispersion = 0.467
Explanation:
Computing the absolute value of dispersion and the formula is as:
Absolute value of dispersion = Quartile deviation
whose formula is
= Quartile 3 - Quartile 1 / 2
where
Quartile 3 is Rs 55,000
Quartile 1 is Rs 20,000
So, putting the values above:
Absolute value of dispersion = Rs 55,000 - Rs 20,000 / 2
Absolute value of dispersion = Rs 35,000 / 2
Absolute value of dispersion = Rs 17,500
Now,
Computing the relative value of dispersion and the formula is as:
Relative value of dispersion = Co-efficient of Quartile deviation
whose formula is
Relative value of dispersion = Quartile 3 - Quartile 1 / Quartile 3 + Quartile 1
So,
Relative value of dispersion = Rs 55,000 - Rs 20,000 / Rs 55,000 + Rs 20,000
Relative value of dispersion = Rs 35,000 / Rs 75,000
Relative value of dispersion = 0.467
