When stratification is authorized, must statements be presented in percentages?

The correct answer indicates that presenting statements in percentages when stratification is authorized is not a requirement. Stratification itself refers to the process of dividing a population into different subgroups for analysis or reporting purposes, and while percentages can be a useful way to convey information about these subgroups, they are not mandated as the only means of representation.

In practice, data can also be presented in other formats, such as counts, rates, or raw numbers, depending on the context or the specific needs of the audience. This flexibility allows for the conveyance of information in a way that best meets the objectives of the analysis or the preferences of the stakeholders involved.

The understanding of when and how to present stratified data is important for effective communication and decision-making, and knowing that percentages are not always required enables professionals to choose the most appropriate method based on the specific circumstances.
