Compute the suitable average from the following data
Income (in Rs.): Below 100 100-150 150-200
No. of persons:
15
25
40
200-400
above 400
20
10
Answers
Answer:
Highest value (H)= 35
Lowest value (L) = 15
Range= Highest value − Lowest value
i.e. R= H− L
Substituting the given values in the formula
R= 35 − 15= 20
Coefficient of Range is as follows:
CR =
H-L
H+L
or, CR =
35-15
35+15
=
20
50
⇒ CR =0.4
Hence, the range (R) of the above data is 20 and coefficient of Range (CR) is 0.4
