Asymmetry, Radial Symmetry, and Bilateral symmetry.
Can you come up with examples in Nature where asymmetry is both preferred and essential, such as the liver or the stomach?
In terms of SQL, Skewness is an asymmetry in the distribution of the data values or how the value is distributed accross. Consider a table employees where you have millions of employee records and a column in that table which have either a value as 0 or 1 (F or T). Now consider out of one million records, the 1 value is applicable for only 2000 employees and the rest are having value as 0. This asymmetry or inproportionate data tells us that the column contains highly skewed data.
Skewness is a measure of the extent to which the probability distribution of a random variable lies more to one side of the mean, as opposed to it being exactly symmetrical.If μ and s are the mean and standard deviation of a random variable X, thenSkew(X) = Expected value of [(X - μ)/s]3
