Verbal Labels' Information
Verbal labels can provide different lengths and amounts of information:
Non-conceptual labels require a previous specification of the type of measurement concept. (‘‘Not at all’’ and ‘‘Completely’’).
Scales can provide conceptual labels like ‘‘Not at all satisfied’’.
Verbal labels can also provide information about the object and/or the subject under evaluation. (An example of objective label would be ‘‘Not at all satisfied with my job’’, and of subjective label, ‘‘I am not at all satisfied’’).
A full informative label would be ‘‘I am not at all satisfied with my job’’.
