Distribution

A distribution, also referred to as a 'frequency distribution',  is a descriptive statistical application that is a way of displaying large sets of data to provide an accurate picture.  It shows the number of occurrences of a type of data among various classes to present raw data in a more usable form. Distributions should have no fewer than 6 and no more than 15 classes. Classes should be selected that will accommodate all the data and each item should be able to go into only one class. The classes should be of as equal length as possible.

• A numerical or quantitative distribution sorts or groups data according to numerical size.
• A categorical or qualitative distribution sorts according to categories, such as geographic location, etc.
