sample and the observations that were made. These summaries can be either quantitative, i.e. summary statistics, or visual, i.e. easy-to-understand graphs. These summaries can either form the basis of the initial description of the data for further statistical analysis, or stand on their own for a particular survey.<\/p><p>For example, basketball shooting percentage is a descriptive statistic that summarizes the performance of a player or a team. This number is the number of shots taken divided by the number of shots. For example, a player who shoots 33 % makes about one in three shots. The percentage summarizes or describes several discrete events. Also consider the cumulative grade point average. This single number describes a student&#039;s overall performance across all of their course experiences.<\/p><p>The use of descriptive and summary statistics has a long history, and indeed the simple tabulation of populations and economic data was the first way the subject of statistics arose. More recently, a set of synthesis techniques have been formulated under the title of exploratory data analysis: an example of such a technique is the box plot.<\/p><p>In the business world, descriptive statistics provide a useful summary of many types of data. For example, investors and brokers can use a historical account of performance behavior by performing empirical and analytical analysis on their investments to make better investment decisions in the future.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-15509 size-medium\" src=\"https:\/\/complex-systems-ai.com\/wp-content\/uploads\/2022\/04\/describe_cap.xml_Graph_cmd2o2-300x200.png\" alt=\"descriptive analysis\" width=\"300\" height=\"200\" title=\"\" srcset=\"https:\/\/complex-systems-ai.com\/wp-content\/uploads\/2022\/04\/describe_cap.xml_Graph_cmd2o2-300x200.png 300w, https:\/\/complex-systems-ai.com\/wp-content\/uploads\/2022\/04\/describe_cap.xml_Graph_cmd2o2-18x12.png 18w, https:\/\/complex-systems-ai.com\/wp-content\/uploads\/2022\/04\/describe_cap.xml_Graph_cmd2o2.png 578w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Theory Homepage Wiki I.
