1.	The frequency distribution of daily income , (in thousand of 80 shops of an area is as follows. Find the absolute and the relative measure of range of daily income from it.Daily income (thousand ₹)5 - 910 -1415 - 1920 - 2425 - 2930 - 34No. of shops11201713127
Answer» Here, x_H = Upper limit of the last class 30 – 34 = ₹ 34 x_L = Lower limit of the initial class 5-9 = ₹ 5 Absolute measure of range of age: R = x_H – x_L = 34 – 5 = ₹ 29 thousand Relative measure of range of age: Coefficient of range = \(\frac{x_H−x_L}{x_H+x_L}=\frac{R}{x_H+x_L}\) = \(\frac{29}{34+5}\) = \(\frac{29}{39}\) = 0.74

Answer»

Here, x_H = Upper limit of the last class 30 – 34 = ₹ 34

x_L = Lower limit of the initial class 5-9 = ₹ 5

Absolute measure of range of age:

R = x_H – x_L

= 34 – 5 = ₹ 29 thousand

Relative measure of range of age:

Coefficient of range = \(\frac{x_H−x_L}{x_H+x_L}=\frac{R}{x_H+x_L}\)

= \(\frac{29}{34+5}\)

= \(\frac{29}{39}\)

= 0.74
