Ratio Level of Measurement

Definition

Ratio level of measurement is similar to interval level, as it allows for meaningful comparisons and equal intervals. However, ratio level also has a true zero point which represents an absence or complete lack of the measured attribute.

Analogy

Imagine ratio level as measuring money in your bank account. You can make meaningful comparisons (e.g., $1000 is more than $500) and have equal intervals ($100 difference), but having $0 means you have no money at all.
