The index of qualitative variation (IQV) is calculated by dividing the number of distinct categories in a dataset by the total number of observations. This produces a value between 0 and 1, where 0 indicates complete uniformity (i.e. all observations fall into the same category) and 1 indicates maximum diversity (i.e. each observation falls into a different category). Therefore, the best choice is C, as it correctly states that the IQV can vary from 0.00 to 1.00.
