Given : mean and coefficient of variation of data are 10 and 5%.
To find : standard deviation
Solution:
using the formula
Coefficient of Variation = (Standard deviation /Mean) * 100 %
Coefficient of Variation = 5%.
Mean = 10
Standard Deviation = SD
putting values in formula
=> 5 = (SD/10) * 100
=> SD =5/10
=> SD = 0.5
standard deviation is 0.5
