Question

Quizplus · Accepted Answer

The highest level of measurement is ratio, which requires a scale with a true zero point. Age can be measured using a ratio scale if respondents are asked to provide their exact age in years (an open-ended item), allowing for precise calculation of ratios such as age compared to income or years of experience. Other options such as age range categories (C and D) and ordinal scales (C) do not allow for precise ratios, and nominal scales (E) would only provide categories without any ordering or numerical values.
