प्रश्न
In a town, 25% of the persons earned more than Rs 45,000 whereas 75% earned more than 18,000. Calculate the absolute and relative values of dispersion.
उत्तर
Absolute values of dispersion
Range = L - S
= 45,000 - 18,000 = Rs 27,000
Relative Value of Dispersion
Coefficient of Range = `("L - S")/("L + S")`
= `(45000 - 18000)/(45000 + 18000)`
= 0.428
