Graphical Descriptive Techniques

Here is the introduction to this website:

"All economic decisions must be made in the present under conditions of uncertainty about the future.   Thus, even if economic agents are able to formulate a

rational strategy for achieving their objectives, they face unpredictable events in the future as they attempt to implement the strategy.  Statistical analysis provides a method of improving the possibility of success by incorporating better information from past events.

The first step in the process of statistical analysis is the identification of the population of interest.  Out of the undifferentiated natural and social environment, certain characteristics are defined and then applied to select out objects of interest.  In economics, these objects are often human beings, typically described as economic agents, although the population of interest may also be outcomes of the economic relationships between and among human beings, such as incomes, prices or quantities of output of particular commodities.  The unpredictable quantitative nature of certain objects, again incomes,  prices and output come to mind, defines such objects, for statistical purposes, as variables.  Collections of actual measurements of variable values is called data.

Data, which is by necessity information about the past, is the raw material that can be used to generate useful information for assessing future outcome probabilities. Raw data is rarely informative enough to be of immediate use.  In order for this data to serve this purpose, it must be transformed.  A first step in such a transformation may be the reorganization of the data into numerical categories and the subsequent presentation of this categorical information in graphical form.  What are some ways of doing this?"

Let me know if I understood your question correctly?

I suppose that the phrase "descriptive statistics" might also be relevant to your question because descriptive statistics are statistics that quantitatively "describe" or summarize features of a collection of information or "data". As for the details of descriptive statistics, the following link would be a good reference:
