Solution
The correct option is C 0.55
Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.Range = H - L In the given series, H= 34 and L+ 10 Range = 34-10 = 24.Coefficient of range is found by dividing the range with the sum of highest and lowest value of the series. Coefficient of range (CR) = R/ (H+L) =24 / (34+10) = 24/ 44 = 0.55
Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.
Range = H - L
In the given series, H= 34 and L+ 10
Range = 34-10 = 24.
Coefficient of range is found by dividing the range with the sum of highest and lowest value of the series.
Coefficient of range (CR) = R/ (H+L)
=24 / (34+10)
= 24/ 44 = 0.55
