eliminated‚ that is‚ . This statistic ranges from -1 to +1. Absolute values above 0.2 indicate great skewness (Hildebrand‚ 1986). Skewness has also been defined with respect to the third moment about the mean: ‚ which is simply the expected value of the distribution of cubed z scores. Skewness measured in this way is sometimes referred to as “Fisher’s skewness.” When the deviations from the mean are greater in one direction than in the other direction‚ this statistic will deviate from zero in

Price Elasticity: Price Elasticity is used to explain the degree of responsiveness of the demand for a product to a change in its price. Ep=Percentage change in quality demanded/Percentage change in price (Ep=Price Elasticity) Practical applications of Price Elasticity: 1) Helps in fixing the prices of different goods: It helps a producer to fix the price of his product.
