Quizplus · Accepted Answer

The number of years that a couple has been happily married can be measured on an interval-ratio scale because it represents a continuous variable with a meaningful zero point (the start of the marriage). Nominal data refers to categories without any inherent order, and ordinal data refers to categories with an inherent order but where the distances between the categories are not necessarily equal. "Ordinary level data" is not a recognized term in statistics.
