검증된 단계별 안내1
Understand the four levels of measurement: Nominal, Ordinal, Interval, and Ratio.
Nominal level classifies data into distinct categories without any order (qualitative only).
Ordinal level classifies data into categories that have a meaningful order or ranking but the intervals between ranks are not necessarily equal; it can describe both qualitative (e.g., satisfaction ratings) and quantitative data (e.g., class ranks).
Interval and Ratio levels are used for quantitative data where numerical differences are meaningful, with Ratio having a true zero point.
Therefore, the level of measurement that can describe both quantitative and qualitative data is the Ordinal level.
