For the purposes of this paper, all data values in Study Data Tabulation Model (SDTM) datasets are considered to be observed. This is despite the fact that in actuality a data value may have been derived prior to or during the creation of the SDTM datasets. For example, an SDTM value of LDL cholesterol derived by the Friedewald calculation from

Scientific investigations produce data that must be analyzed in order to derive meaning. Because data patterns and trends are not always obvious, scientists use a range of tools—including tabulation, graphical interpretation, visualization, and statistical analysis—to identify the significant features and patterns in the data.
