For demonstration, in the study is the distinction in noted absenteeism between psychiatric and obstetrics doctors are sufficient to resolve that there is significant distinction in absenteeism between the two units? There are two possibilities: The first likelihood is that the distinction between the two assemblies is an outcome of possibility factors (Borg, 1997).
