Ordinal Level of Measurement

Definition

Ordinal level of measurement is a type of measurement scale where variables are ranked or ordered based on their attributes. The order matters, but the differences between values may not be equal or meaningful.

Analogy

Imagine ranking different ice cream flavors from your favorite to least favorite. The order matters, but the difference in preference between each flavor might not be consistent - just like ordinal level data.
