if coefficient of skewness is zero then distribution is symmetric or zero skewed.

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.

lol...u seem to be studying in swinburne?? may be coincidence...! I was looking for the same stuff :P

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 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'.

For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.

The Lorenz curve was developed by Max O. Lorenz. The Lorenz curve is a visual representation in economics which displays the income distribution of a nation graphically. On the y-axis, you have income distribution (either as a percentage, or in decimal form); on the x-axis, there is population distribution of total wealth. There is an upward sloping, 45 degree reference line that shows perfectly equal distribution of wealth (i.e 25% of the lowest income earners have 25% of the nation's income). From the Lorenz curve, you can calculate the Gini coefficient; the closer the coefficient is to zero, the more distributed the income of a nation is.
