The co-eff. Of variation of a data is 58%, S.D. of the data is 2.32 then the A.M. of the data is

S.D. of a data is 21.2, mean is 36.6, then find its C.V.

Co-efficient of variance of one data is 45% and mean is 12 then S.D. is 5.4

C.V. of a data is 69%, S.D. is 15.6, then find its mean.

If the co-efficient of variation and S.D of a data are 35% and 7.7 respectively, then the mean is ___.

The coefficient of variation for the following data is

The variance of a set of data is 121. Then the standard deviation of the data is: A. pm 11 B. 11 C. 21 D. 60.5

S.D. of a data is 6. When each observation is increased by 1, then the S.D. of new data is

If the mean and coefficient of variation of a data are 4 and 87.5 % then the standard deviation is
