The distribution coefficient is the ratio of concentrations of a compound in the two phases of a mixture of two immiscible liquids at equilibrium. They are measered by their hydrophilic (water loving) or hydrophobic (water hating) properties. In Pharmaceutical science. Finding the DC of a drug is useful for example in estimating distribution of the drug within the body. (WIll it pass the lipid bilayer, or the blood brain barrier in the brain).

The spreading coefficient is often applied in the field of pharmacy. Film coats are spread over tablets and lotions with mineral oils are spread on skin using surfactants. The spreading coefficient is the difference between the work of adhesion and the work of cohesion.
if coefficient of skewness is zero then distribution is symmetric or zero skewed.
The distribution coefficient is usually applied in the octanol-water partition. It is commonly used in the liquid-liquid extraction. Distribution coefficients are also called partition coefficients.
Coefficient of varation
It depends on what the underlying distribution is and which coefficient you want to calculate.

A measure of skewness is Pearson's Coefficient of Skew. It is defined as: Pearson's Coefficient = 3(mean - median)/ standard deviation The coefficient is positive when the median is less than the mean and in that case the tail of the distribution is skewed to the right (notionally the positive section of a cartesian frame). When the median is more than the mean, the cofficient is negative and the tail of the distribution is skewed in the left direction i.e. it is longer on the left side than on the right.

The answer is r.Actually 'r' is the usual symbol for the correlation coefficient statistic calculated for a sampleof paired values. The correlation coefficient for a population of pairs of random variables distributed according to a binomial normal distribution is usually denoted by the Greek letter 'rho'.
