This statement is false because the range of measurement in an index is not always an advantage. It can be a disadvantage if it includes extreme categories that have very few cases, thus making it difficult to make meaningful comparisons or draw conclusions based on those categories. Tammy needs to consider the balance between having a wide range of measurement and having enough cases in each category.
