The Range is the difference between the lowest and highest values. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Bivariate distribution is the combined probability distribution of two randomly different variables. Normally, these can be plotted graphically on x and y axes so their relationship can be analyzed and any relevant causal effect can be identified. This type of data analysis is useful in risk management.
 

The total frequency of all classes less than the upper class boundary of a given class is called the cumulative frequency of that class. “A table showing the cumulative frequencies is called a cumulative frequency distribution”. There are two types of cumulative frequency distributions: less than cumulative frequency distribution and greater than frequency distribution.
 

A frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.

Median is a positional average unlike mean, dispersion etc which are magnitudinal averages. 

A frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample. Too many classes or too few classes might not reveal the basic shape of the data set, also it will be difficult to interpret such frequency distribution.

A Frequency array is an array of frequencies according to variate values, that is to say, a frequency distribution. The term “array” is often used for the individual frequency distributions which form the separate rows and columns of a bivariatefrequency table. The raw data when put in ascending or descending order of magnitude is called an array or arrayed data.

When the data is presented in some specific order and sequence it is called as a statistical series. An ordered sequence of data samples in numerical form used to predict or demonstrate trends through time and space is called statistical series

Data classification is the process of organizing data into categories for its most effective and efficient use. A well-planned data classification system makes essential data easy to find and retrieve. This can be of particular importance for risk management, legal discovery, and compliance.

A Comprehensive Data Definition refers to a formal data definition that provides a complete, meaningful, easily read, readily understood definition explaining the content and meaning of data.
