Question

Find the coefficient of variation of a data from the following information:
Karl Pearson's coefficient of skewness = 0.65, mean = 51 and median = 45​

Answer 1

Step-by-step explanation:

karl Pearson's coefficient of skewness

=3(mean -median)/sd

sd is standard deviation

=> 0.65 =3(51-45)/sd

sd = (,3×6)/0.65=27.69

coefficient of variation = sd/mean

= 27.69/ 51 = 0.54
