Question

Coefficient of standard deviation is 0.506 and standard deviation is 12.65 then its mean is ...​

Answer 1

Answer:

The coefficient of variation represents the ratio of the standard deviation to the mean, and it is a useful statistic for comparing the degree of variation from one data series to another, even if the means are drastically different from one another

Answer 2

Answer:

        Mean  = 25            

Step-by-step explanation:

Given data:

coefficient of standard deviaton = 0.506

              and standard deviation = 12.65  

here we need to find Mean of the data  

for a data the formula for coefficient of standard deviation is given by

coefficient of standard deviation = standard deviation ÷ mean  

Let x be the mean of the data

from given data    ⇒   0.506 =   12.65 ÷ x

                                      $0.506 = \frac{ 12.65 }{x}$  

                                           $x = \frac{ 12.65 }{0.506}$  

                                            x =  25
