Editing Nominal and Ordinal Values

DataLab supports four different types of measurement scales: nominal, ordinal, interval, and ratio scaled variables. The type of a variable (column of the data matrix) can be set by the user in the matrix viewer. For nominal and ordinal variables the user may additionally specify the corresponding categorial names (again, in the matrix viewer, by clicking the star-button right to the scale type).

DataLab supports up 25 nominal/ordinal identifiers for each variable. When you click the star-button right to the scale type a window is opened which lets you enter the nominal or ordinal identifiers. You can edit or add an identifier by clicking into the corresponding field and entering the new string. In order to undefine an identifier, just clear it and leave it empty. Undefined identifiers are indicated by the string "(undefined)".

Hinweis: Categorial assignments can be re-sorted by "drag & drop". The re-sorting changes the assignment between identifiers and ordinal numbers (the data stay the same, only the corresponding identifiers change). Thus re-sorting should be performed only either before entering the data, or if the current assigments are wrong.
