A significant characteristic of data sets is the method or methods the data is distributed, or how each element of the data varies from the central point or 'mean', which is an average calculation of the data set. There are numerous methods of measuring the variance of the data. The most common of these methods is the 'standard deviation', which provides a calculated average distance for each of the data elements from the 'mean'. Listed are other forms of data distribution measuring forms:

Standard Deviation- calculated average distance for each of the data elements from the mean

Range- difference between the highest and lowest data element

Variance- square of the standard deviation
