Is cholesterol level a qualitative variable?

Cholesterol level is not a qualitative variable; it is a quantitative variable. Specifically, it is a continuous variable that can be measured and expressed numerically in units such as milligrams per deciliter (mg/dL). Qualitative variables, on the other hand, represent categories or qualities, such as "high," "medium," or "low" cholesterol, which are descriptive rather than numerical.
