Answer -
25% of the persons earned more than тВ╣ 45,000. This implies that upper quartile Q3 = 45,000 75% earned more than 18,000. This implies that lower quartile Q1 =18,000
Absolute Measure of Dispersion = Q3 тАУ Q1 = 45,000 тАУ 18,000 = 27,000
Relative Measure of Dispersion
Co-efficient of Quartile Deviation
