If the data are moderately non-symmetrical, then which one of the following empirical relationships is correct?

2 x Standard deviation = 5 x Mean deviation

5 x Standard deviation = 2 x Mean deviation

4 x Standard deviation = 5 x Mean deviation

5 x Standard deviation = 4 x Mean deviation

S.D=5/4 M.D

4 x Standard deviation = 5 x Mean deviation
Hence option3 is correct.
