from a large pool of data. One such procedure is “Descriptive Statistics”, which provides useful statistics pertaining to a variable like mean, median, mode, standard deviation, kurtosis, skewness etc. These statistics provide information about central tendency, dispersion and skewness of the data and are very useful information about the variable under consideration.
