Mode – the value or observation that occurs most regularly in a data set. In some application the Range is reported while in the productivity, however in different software programs the particular minimum and optimum prices are reported.

Skewness – measures the amount and path of proportion or asymmetry of the submission. But in real life of research, typical distributions are difficult to come by. Kurtosis – procedures how peaked a distribution is as well as the lightness or heaviness of the tails of the submission. In statistics, a normal circulation features a kurtosis value of zero (0) and it is reported to be mesokurtic.
